] | What is a good implementation of a IsLeapYear function in VBA?
**Edit:** I ran the if-then and the DateSerial implementation with iterations wrapped in a timer, and the DateSerial was quicker on the average by 1-2 ms (5 runs of 300 iterations, with 1 average cell worksheet formula also working). | ```
Public Function isLeapYear(Yr As Integer) As Boolean
' returns FALSE if not Leap Year, TRUE if Leap Year
isLeapYear = (Month(DateSerial(Yr, 2, 29)) = 2)
End Function
```
I originally got this function from Chip Pearson's great Excel site.
