Check if a year is a leap year with formula
Supposing you have a list of year in the worksheet, the following long formula can help you to determine if a given year is a leap year or not. Please do as this:
1. Besides the year cells, in a blank cell, enter this formula:
=IF(OR(MOD(A2,400)=0,AND(MOD(A2,4)=0,MOD(A2,100)<>0)),"Leap Year", "NOT a Leap Year"), (A2 contains year that you want to apply this formula, you can change it to your need) see screenshot:
2. Then drag the fill handle over to the range that you want to contain this formula, and all the years have been checked if they are leap years or not.
Note: If the relative cell is blank, this formula will show Leap Year, too.

You can also create User Defined Function to check if the year is a leap year, you can complete it as these:

2. Click Insert > Module, and paste the following code in the Module Window.
VBA code: check if a year is a leap year
Function IsLeapYear(pYear As Integer) As Boolean
'Update 20140623
If (pYear Mod 4) = 0 And (pYear Mod 100) <> 0 Or ((pYear Mod 400) = 0) Then
IsLeapYear = True
Else
IsLeapYear = False
End If
End Function
3. Then save and close this code, go back to your worksheet, and enter this formula: =isleapyear(A2), see screenshot:
4. Then drag the fill handle to the cells that you want to contain this formula, and all the years have been checked off, the FALSE stands for not a leap year and the TRUE indicates a leap year. See screenshot:
