Carlos Bittar, none
no web site, sorry

This function determines the interval between two dates.

Sample Input:
CF_DateInterval (04/20/1980; 02/15/2018)

CF_DateInterval (12/31/2017; 02/15/2018)

CF_DateInterval (12/10/2017; 12/14/2018)
Sample Output:
37 years 9 months 25 days

1 month 15 days

1 year 4 days

 Then copy & paste into FileMaker Advanced's Edit Custom Function window.


This function determines the interval between two dates, even considers leap years. Due to the way both dates of the time interval are broken down, this function can be used in mm/dd/yyyy and dd/mm/yyyy format.
Date 2 must be iqual or greater than Date 1.
Please do not change the order of the calculations, otherwise it won't work.
I hope you'd liked this.

Note: these functions are not guaranteed or supported by Please contact the individual developer with any questions or problems.

This is my Custom Function and I want to edit it


I'd calculate year to day order, so on the first sample it would be 37 years 9 months 26 days.
(37 years and 9 month after 4/20/1980 is 1/20/2017, so 2/15/2017 is 26 days after.)
