How to Find Last Day of the Month in Excel?

We are always eager to know the first day of the month but sometimes we often need to know the last day of the month in excel. This is specifically happening in the case where we have to pay some dues at the end of the month and we want to know, how much time do we still have before the debt becomes due?

In such cases, we will use the inbuilt function of excel that is called the EOMONTH. This function will help us to return the last date of the month.

The functionality of this function is not only restricted to know the last date of the current month but we can choose to know the last day of the previous month in excel, next month and we can also choose to know the last day of the month at the Custom defined gap of months.

EOMONTH is also the inbuilt functions in excel that belongs to the “Date & Time” class of functions. This function does not need much of arguments as input to give us the last date of the month. We just need to enter the beginning date and then specify the month for which we need the last date of the month.

=EOMONTH (Date, Months) or = EOMONTH (1/1/19,0)

This function will return the last date of the same month that is Jan in this case. Since we have specified “0” in the months excel will calculate the last date for the same month of Jan.

= EOMONTH (Date, Months+1)   or = EOMONTH (1/1/19,1)

• Since now we have specified “1” in the month’s arguments, Excel will calculate the last date of the next month.
• Since Jan is the month of the date, excel will add one month to Jan and will give us the last date of FEB month.
