We can use the EOMONTH and DAY functions to get the number of days in the month when we already have a single date. The steps below will walk through the process.
Figure 1: Result of using the DAY and EOMONTH functions
General Formula
=DAY(EOMONTH(date,0))
Formula
=DAY(EOMONTH(B5,0))
Setting up the Data
- We will set up data by inputting our Dates in Column B
- Our result, which is the Number of days in a month will be returned in Column C
Figure 2: Setting up the Data
Calculate the number of days using EOMONTH and DAY

Figure 3: How to get the days of the month
- We will click on Cell C5 again
- We will double click on the fill handle tool which is the small plus sign you see at the bottom right of Cell C5. Select and drag down to copy the formula to other cells.
Figure 4: Result of using the DAY and EOMONTH functions
Explanation
=DAY(EOMONTH(B4,0))
Our DAY function is always equal to the number of days in the month. The EOMONTH function checks the date in Cell B4 and returns the date corresponding to the last day of the month we specified. Next, the DAY function works on the data derived by the EOMONTH and return with the total number of days for that month.
