Hi - I would like to be able to sum the individual digits in a date - e.g, a given date = the sum of its individual digits. Some examples:
Date: 7/13/1969 = 7 + 1 + 3 + 1 + 9 + 6 + 9 = 36
Date: 12/20/2019 = 1 + 2 + 2 + 0 + 2 + 0 + 1 + 9 = 17
I have some idea that I could convert the dates to text, then do a “value” of each digit, but nothing I’ve tried has worked. I’m grateful for any ideas!
Hi @Cathy_Crosman! Welcome to the community! :partying_face: :partying_face: :partying_face:
This formula does what you are looking for:
IF(Date, RIGHT(DATETIME_FORMAT(Date, 'MM', 1)) + LEFT(DATETIME_FORMAT(Date, 'MM', 1)) + RIGHT(DATETIME_FORMAT(Date, 'DD', 1)) + LEFT(DATETIME_FORMAT(Date, 'DD', 1)) + RIGHT(DATETIME_FORMAT(Date, 'YYYY', 1)) + LEFT(DATETIME_FORMAT(Date, 'YYYY', 1)) + VALUE(MID(DATETIME_FORMAT(Date, 'YYYY'), 2, 1)) + VALUE(MID(DATETIME_FORMAT(Date, 'YYYY'), 3, 1)))
Replace ‘Date’ in the formula with your date field.
All the best with it.

That is phenomenal! I’ll have to dissect that to see how it works, but it works beautifully! Thank you so much.

Great formula, and the same approach I was thinking of.
I noticed that you use VALUE with MID but not with RIGHT or LEFT. Is there a reason for this?
If the user sometimes gets unexpected results, the formula might want to include setting the timezone in DATETIME_FORMAT.
