Counting the Days (or Months or Years)
The example shown above counts the number of days from Start to Today. Actually you are counting the number of day changes over the period from Start to Today. How many changes were there in months or years? Use the INTCK function to determine this.

Example:

Start = "05JUL1990"d;
Num_Mons = Intck("MONTH", Start, Today());
Num_Yrs = Intck("YEAR", Start, Today());
