=DATE(YEAR(A2),((INT((MONTH(A2)-1)/3)+1)*3)+1,1)-1

would anyone be able to explain how the above formula works? its works for me but i would really like to know why and how.

Thanks!

I need to calculate in between two different dates using per day value for 3 quarter how much? . What formula in excel

Alternative Method To calculate the end date of a quarter based on a date:

=EOMONTH(EDATE(DATE(YEAR(A2),FLOOR(MONTH(A2)-1,3)+1,1),3),-1)

I need to calculate the number of days from a specific date to the end of the quarter. However, our fiscal quarters are not standard, and the fiscal year starts May 1st. I can calculate days remaining to a standard quarter end, but how do I calculate to a different quarter schedule. For example, 4/2/2016 should produce a fiscal quarter end of 4/30/16, 11/6/16 should produce a fiscal quarter end of 1/31/17, etc. We attempted this with EOMONTH function, but that does not convert well between excel and sharepoint. Any help would be really appreciated!
