  1. Hi I need a formula to know the number of days a project is delayed
    Ex.
    No. of day required days = 7 days
    Start date = March 20, 2017
    End date = March 24, 2017

    What formula can I use to reflect no. of days a project is advanced or delayed. Excluding Sat Sun and holidays

    1. Hi Ron,

      Let's say that start day is in A1, end date is in B1.
      First of all, you need to count the number of working days between your dates in C1:
      =NETWORKDAYS(A1,B1)
      You can find out how to exclude weekends and holidays here.

      Then, depending on how you want the result to return:
      a) if as a text in D1, enter the next formula there:
      =IF(C1<=7,"Advanced","Delayed")

      b) if you want to fill C with a colour, create formatting rules using formulas:
      =AND($C1<=7,$C1<>"") (green colour for advanced)
      and
      =AND($C1>7,$C1<>"") (red, meaning delayed)
      Apply the formatting for =$C:$C column.

      Hope it helps!

  2. I need a formula to calculate a date with a number if that number is greater than 0.

    4/27/2016 | 73 | __________
    7/14/16 | 0 | __________

    I tried using SUMIF but no luck. Is this possible?

  4. Well after googling several add month solutions it appears that the 2 solutions actually do not work as I would expect them.

    How do you actually get the last day of the month based on the last day of the previous month ?

    If I add 1 month for example to the last day of September 2015 i.e:
    A1=date(2015,09,30) := 2015-09-30
    A2=date(year(A1),month(A1)+1,day(A1)) := 2015-10-30
    This is 1 day before the last day of October 2015.
    So it isn't adding 1 month but 1 month minus 1 day.

    I was expecting to get as a result: 2015-10-31

    Same result using EDATE
    A1=date(2015,09,30) := 2015-09-30
    A2=EDATE(A1,1) := 2015-10-30

    The only way I found to get this to work i.e: get the date of the last day of the month based on previous last day of the month is:

    A1=date(2015,09,30) := 2015-09-30
    A2=DATE(YEAR(A1+1),MONTH(A1+1)+1,DAY(A1+1))-1 := 2015-10-31

    1. The EOMONTH formula will return the last day of the month, and you can specify how many months before or after your original date. e.g. if your original date is in cell A1, =EOMONTH(A1,3) will return the last day of the month three months later. I hope that helps.

  5. Hi,

    I have a list of dates (column I) which show when training was completed. In column J I have my formula for adding 1 year to the date in column I for when the training is to be renewed. In some of column I i don't yet have a date, in column J this comes up as 31-Dec-00 as there is no data inputted in column I. Can i add something to my formula to say if the cell in column I is empty then for the cell in column J to stay blank?

    The formula i'm using in column J is: =DATE(YEAR(I2)+1,MONTH(I2),DAY(I2))

    Thanks

  6. I want to subtract number of year from Date 01-Nov-17 and 34 year

  7. Hi!

    I'm using the following formula: =DATEDIF(C6,D6,"d") to calculate the difference between days. Works well. However, when the date is the same in both cells, is there a way for me to add "1" to show a calculated answer of 1 in the final field? (Trying to account for number of days traveled in a month and, although it's the same day, it should still count as 1 day.)

    Thanks!

  13. I am using the formula
    =I2-TODAY()

    That gives me a number value, but I cannot get it to change to date.

  14. That is not what I'm asking. I have a spreadsheet with hire date, 3 month eval, 6 month eval, and 9 month eval. I want to take today's date and subtract it from the due date. If it is more than 5 days, I want the cell to turn red. If it is 5 days or less, I want the cell to turn yellow. Anything over 5 days will not change.

  15. In gregorian date if we mention date as 1/13/15 then it can show as 13.01.2015 and while applying Filter it will show us years 2015 2014 2013, by selecting the year we will have months then dates... same way I wish to have for Hijri (Arabic) dates as by typing 2/20/38 it shall show as 20.02.1438 and by applying Filter it should show 1438 1437 1436, then by selecting year it should show months then dates.... Please advise

  16. I want to take hire date and do evaluation at 3 months, 6 months and 9 months. I entered the hire date in b2 and want the values in c2, e2, and g2. I used the formula of 10/5/2016 as date in b2 with =sum($b2)+90)) to get the 30 day,=sum($b2)+180))for 6 months, =sum($b2)+270))for 9 months.

    Now in column d2, f2 and h2, I want it to highlight the cell red if date in c2 is more than days overdue and yellow if date is between 1 and 5 days until due. If evaluation is done or if evaluation is more than week from due, cell remains white background.

    How do I get it to subtract the due date from today's date and set the cell to change colors?

  17. Hi, how do I subtract 3 months from an end date given and the result must be the month end date instead beginning of the month?

    For example:
    3 months prior to due date Due date
    31/10/2017(I must get this result) 31-Jan-18
    01/10/2017(this result must be 30/09/17) 31-Dec-17
    30/08/2017(this result must be 31/08/17) 30-Nov-17
    (Formula =DATE(YEAR(M36), MONTH(M36) - 3, DAY(M36))

  18. Pls tel me the formula to get

  22. Hello,

    I am trying to calculate a result in where I can determine an expiration date of a specific date within 1 month.

    Example- Start Date is 2/17/2016 and End date is 02/16/2017. I would like to create a formula that will be able to tell me when the end date expires
    1 month before.

  23. Hi i am trying to work out days elapsed on a task

    Start Date - Completed date (this is easy) but if the item is not closed and no date is entered i want Todays date to be default

    Please help

  24. I can not for the life of me figure out how to do this!
    I want to track how long staff spend on task.
    They put the date & time started and the date & time they finish.
    I need to get the total hours & minuted (hh:mm)working.
    Deduct :30 for break and 1:00 for lunch. Then if the start and finish is greater than a day, subtract the 15 hours (overnight)

    H1[START] = 24/11/2016 09:45
    I1[FINISH] = 25/11/2016 08:35
    J1=[TIMEWORKED] ??? (hh:mm)

    Work day is from 06:00 - 15:00
    Break from 09:00 - 09:30
    Lunch from 11:00 - 12:00

    I need to do this macro free. I have been trying to sold this for ages. Looked all over the internet. What I have established is that I need to show the times as general formatting do the calculations and then display the result as hh:mm. My head aches trying to resolve the calculations though.

    Any help, ideas, advice??
    Cheers

  25. Hi all,

    Following this thread and trying to create a list in Column A to reflect a weekly schedule with the value in A3 being the baseline and incrementing A4, A5, etc... by 7 days, simple stuff based on this site... so I thought... ;)

    Desired results
    Cell A3 - 1/10/2017
    Cell A4 - 1/17/2017
    Cell A5 - 1/24/2017
    etc...

    Current configuration
    Cell A3
    - Format: Date (3-14-2012 from Date format Type list)
    - Current value: 1/10/2017

    Cell K1
    - Format: Number
    - Current value: 7

    Cell A4
    - Format: Date (3-14-2012 from Date format Type list)
    - Formula: =DATE(YEAR(A3),MONTH(A3),DAY(A3)+$K$1)
    - Resultant value: #VALUE!

    Investigation
    I'm on Office2016 64-bit on a WINDOWS7 64-bit, i7 CPU/16GB RAM

    If I go to Cell A3 and "drag down" to A4 the date increments to 1/10/2018 so it seems as though it is recognized as a date...

    Looking at the Function bar dialog box when you click on "fx" it shows:

    /snip

    DATE
    Year: YEAR(A3) = #VALUE!
    Month: MONTH(A3) = #VALUE!
    Day: DAY(A3)+$K$1 = #VALUE!

    Formula result =

    /snip

    I then look at "Evaluate formula" and get (CY2017 is the tab name):

    /snip

    Reference Evaluation
    'CY2017'!$A$4 = DATE(YEAR("1-10-2017"),MONTH(A3),DAY(A3)+$K$1)

    The next evaluation will result in an error.

    /snip

    No change if I modify Date "type" format or change "/" to "-"...

    Questions
    Why would the date not format to 1-10-2016 per the selected Date format?
    - I went to a blank cell and modified the cell format to the same as above, when I then enter 1/10/17 it changes to 2001-10-17... huh??

    Appreciate any insight, thanks.

    1. OK, all I can say is WOW... :) I got this to work but it seems to me to have been MUCH more complicated than need be...

      Additional/changed config (from previous post)
      Cell J1
      - Format: Date (*2012-03-14)
      - Current value: 2017-01-10

      Cell A3
      - Format: Date (3-14-2012)
      - Formula: =DATE(YEAR(J1),MONTH(J1),DAY(J1)+0)
      - Resultant value: 1-10-2017

      Cell A4
      - Format: Date (3-14-2012)
      - Formula: =DATE(YEAR(A3),MONTH(A3,DAY(A3)+$K$1)
      - Resultant value: 1-17-2017

      I then drag A4 down to fill out the rest of the year and it works.

      Really feels like this was way more complicated than need be, thoughts?

  26. HI,,,
    Hope you doing well in the best of health. I really like the page, which is much helpfull. I need help please guide me.
    I am doing job at college and we deal majority student matters.
    if a student deposit his/her fee after due date, and due date is e.g 25-09-2016 and deposit date is 27-10-2016. each day after due date will b charge as fine Rs. 100. how i will do it with formula........please help

    1. Hi Naveed,

      Assuming the due date is in A2, and the actual payment date in B2, and the fine is 100 per day, you can calculate the fine amount with this formula:

      =IF(B2>A2, (B2-A2)*100, 0)

      If necessary, you can add the fine to the original amount, which is, say, in cell C2:

      =IF(B2>A2, (B2-A2)*100+C2, C2)

  27. I have a date derived (via formula) in a cell say A2 and I want to have a new date in cell B2 by adding 2 to Cell A2.

    best part.. In one excel sheet I am able to derive it, but on another sheet I am not :(

    Not sure whats the issue. Please help.

    Thanks,
    Manish

  35. Supposing I have a ranges of cells comprising of due dates that fall on weekends, holidays and weekdays. Whenever a due dates fall on holidays or weekends, transactions would commence on the next following working day. I used IF, OR, WORKDAY, and WEEKDAY functions but i found it very difficult to suppress due date that falls on weekdays (not a holiday) from incrementing by one(1)day. I am formulating a formula that would address all of the records at the same time. Hoping for your assistance.

  36. I got a date 12 Feb in Excel column and I want to add the year so it can be 12/02/2016 ?

  37. Hi there...Hope you can help me with the following.

    I want to add a date to a cell. Then in a different cell i want it to work out 6 months from the date in the first cell. IF the date then goes pass our current date, i want it to show red or say expired.

    1. Hi Lorien,

      Supposing you add the first date to A1. Then you can enter the following formula, say in B1, to add 6 months to the first date:
      =EOMONTH(A1, 6)

      And then, you can create a conditional formatting rule with the below formula to highlight the date in B1 with the red color when it goes past the current date:
      =$B1<TODAY()

      For the detailed instructions, please see How to conditionally format dates and time in Excel.

  38. hi please help me, i used =IF(AG2<(TODAY()+2),"DELIVERY DATE",IF(AG2<(TODAY()-1),"DONE","ON GOING")) formula but the result "done" doesn,t work.

    if AG3 is 2 days before delivery date the result is "delivery date" if after delivery date the result is "done" when AG3 has no date the result is "no supplier delivery date" otherwise "on going"

  39. I am trying to subtract two dates to get a calculated time between the dates in MM:dd:hh:mm format to see how long it takes to resolve an ticket. Example:

    Start Date: 05/01/2016 13:24
    End Date: 05/17/2016 18:04

    Should end up with 00:16:04:40, but it comes out as 01:16:04:40, and I can't for the life of me figure out how to make that month be 00 and be more accurate.

    I have found several articles that use the ability to manipulate the month itself, but doesn't describe how to subtract two dates AND round down on the month to show the accurate time between the two dates. Any help here would save what hair I have left. Thanks.

    1. Hi Sandy,

      You can use DATEDIF to get the number of complete months between 2 dates, and then concatenate the results of several functions in 1 formula:

      =DATEDIF(A1,A2,"m") & ":" & DATEDIF(A1,A2,"d") & ":" & TEXT(TIME(HOUR(A2), MINUTE(A2), SECOND(A2)) - TIME(HOUR(A1), MINUTE(A1), SECOND(A1)), "hh:mm")

      Where A1 is the start date, and A2 is the end date.

      The drawback of this approach is that the result is a text string and you won't be able to use it in other calculations.

      1. Yes that's the problem. I do need to be able to add the results of this together to get a total time spent on a ticket. Any other ideas?

        1. Sorry, I have no other idea. To my best knowledge, none of the Excel functions or formats can display a zero month or day.

          As a workaround, you can use 1 column to present the time difference in an easy-to-understand way (DATEDIF formula). And in another column, calculate the time difference with a simple formula like =A2-A1, and display it in hours and minutes [hh]:mm. And then, use that second column to get the total time.

  42. I am looking for a similar calculation as SElizabeth. What I need is a gestational age calculated from a specific due date on a specific date. All I can locate is a formula that gives a calculation based on todays date...which of course will change the resulting value each day. I need for the result to be a fixed value.

    The formula I have is: =FLOOR(279-(K2-TODAY()),7)/7&" weeks "&MOD(279-(K2-TODAY()),7)&" days"

    The K2 value is clients due date. When I try to substitute the TODAY value for a cell that contains the date I want this to calculate off of, I get an error.

    I don't understand excel at all...so I am stuck!

    Any ideas?

    Thanks

  43. I'm trying to develop a spreadsheet of pregnant patients, and I need a formula to calculate today's gestational age from due date. The output would be something like "35 2/7", meaning 35 weeks and 2 days gestation. Here's the Google Sheets formula that does not work in Excel:

  48. hi,

    Wednesday, June 01, 2016
    i want to split day and date so how to possible ?

    1. Hello Hiren,

      If your original values are dates, you can use the following formulas:

      To extract the day of the week: =TEXT(A2, "dddd")
      To extract the date: =TEXT(A2, "mmmm dd, yyyy")

      If your original values are text strings, then use these ones:

      To extract the day of the week: =LEFT(A2, FIND(",", A2)-1)
      To extract the date: =RIGHT(A2, LEN(A2)-FIND(",", A2)-1)

  49. Thanks Svetlana, im new to this!

  50. =IFERROR(MONTH(BA5),"") IS RETURNING 1

    1. Hi Dan,

      Just use IF instead of IFERROR:

      =IF(BA5="","", MONTH(BA5))
