Rounds the date to the closest first day of the month. When the day is smaller or equal to 15 it goes to the first day of TheDate. If it's bigger than 15 then it goes to the next month's first day.

Sample Input:
RoundDate ( "3/28/2017" )

RoundDate ( "3/14/2017" )

RoundDate ( "3/15/2017" )
Sample Output:
4/1/2017

3/1/2017

3/1/2017


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

Description:

If the date is is smaller or equal to 15 then use the same month's first day.
ex: RoundDate ( "3/14/2017" ) --> 3/1/2017

If the date is bigger than 15 then use the next month's first day of the month.
ex: RoundDate ( "3/28/2017" ) --> 4/1/2017

If the TheDate's month is 12 and TheDate's month is bigger than 15 then go to next year's 1/1/Year (TheDate) +1
ex: RoundDate ( "12/28/2017" ) --> 1/1/2018

IsValid () Does check TheDate if it's a valid date. Gives a blank result if TheDate is not a valid date. Does also check for correct last day of the month and February's correct last day of the month.

Would love some corrections. Purposely did not use Case () in order to reduce calculations as much as possible to keep the function as efficient as possible according to my knowledge.

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

This is my Custom Function and I want to edit it

What about:

If ( IsValid ( GetAsDate ( TheDate ) ) ; Date ( Month ( TheDate ) + ( Day ( TheDate ) > 15 ) ; 1 ; Year ( TheDate ) ) )

Thank you Daniele, I didn't think about using a condition that way in my functions. Thank you!
I put credits for you.
