Supported format specifiers for DATETIME_FORMAT

The DATETIME_FORMAT function will allow you to reformat the data from the date-type field into a string of your specifications. This is written in the form "DATETIME_FORMAT(Datetime, 'format specifier')," in which the format specifier can be something like 'DD-MM-YYYY,' 'YYYY/MM/DD,' 'MM.DD,' etc.

(For more on how to use the DATETIME_FORMAT function in Airtable formulas, please see the article Formulas and date fields.)

The following is a table of the supported format specifiers:

Clarifications

The format specifiers w and W behave slightly differently from one another. W is the "ISO week of year" (see Wikipedia for more details). w is for the "locale week of year" (in our case, according to the Gregorian calendar in GMT). 2/11/21 falls on the 6th ISO week and on the 7th Gregorian week. Behind the scenes, Airtable uses the moment library for date parsing. All of the tokens are documented here.
