Here is a handy trick to calculate last day of any month.
Assuming y and m contain the year & month for which you want to find the last day’s date, write
=DATE(y, m+1,0)
That is right, you can use ZERO (0) as the day.
When you do this, Excel tells us the last day of previous month.
How to calculate last day if I have a date in that month:
Instead of year and month, if you know a date & you want to find what is the last date… then use:
=EOMONTH(date, 0)
How to calculate the last working day of a month?
If you just care about working days.. then use:
=WORKDAY(DATE(y,m+1,1), -1)
This will give us the last working day of a month.
Dealing with holidays:
Very simple. Pass on a list of holidays to WORKDAY as last parameter. Like this:
=WORKDAY(DATE(y,m+1,1), -1, F1:F20)
This assumes, F1:F20 has a list of holiday dates.
Dealing with different weekend types:
Not everyone observes Saturday & Sunday as weekend. For example, I do not work on Tuesdays. You might have Sunday thru Thursday work week. If so,
use WORKDAY.INTL function, like this:
=WORKDAY.INTL(DATE(y,m+1,1), -1, 7)
Weekend type 7 is for Friday & Saturday weekend.
