Forumla to calculate differences in dates
Hi
I am trying to find a formula that will calcualte the number of months between 2 dates but, will also take into account some other rules. For example: if the second date has a day of less the 15 it would calculate that month as 0.5 and if the day is over 15 it will calculate the month as a full month.
Start Date: 01.01.2014
End Date: 14.06.2014
Months worked: 5.5
Start Date: 01.01.2014
End Date: 15.06.2014
MOnths worked: 6
Any help would be really appriciated.
Hi and welcome to the forum
If you want to include years (if the dates go past 1 year), then use this...
=IF(DATEDIF(A1,B1,"y")=0,"",DATEDIF(A1,B1,"y")&" years ")&IF(DATEDIF(A1,B1,"ym")=0,"",DATEDIF(A1,B1,"ym")+IF(DATEDIF(A1,B1,"md")<15,0.5,1)&" months ")
If you dont need the year part, then shorten it to this...
=IF(DATEDIF(A1,B1,"ym")=0,"",DATEDIF(A1,B1,"ym")+IF(DATEDIF(A1,B1,"md")<15,0.5,1)&" months ")
Note, the 2nd example you gave only has a 14-day "remainder"
1. Use code tags for VBA. [code] Your Code [/code] (or use the # button)
2. If your question is resolved, mark it SOLVED using the thread tools
3. Click on the star if you think someone helped you

I've always just done this for calculating difference in dates:
(end date/start date)/365.25
you'll need to format the cell to show a number, the default is a date so you must change it.
Hi and welcome to the forum
I think you meant...(end date/start date)/365.25
(end date-start date)/365.25
and / 365 will give you a decimal of a year, not months
A6=(A5-A4)/365.25
Thanks Ford - this worked perfectly!
