The DATETIME_FORMAT function overview
The DATETIME_FORMAT function allows you to reformat data from a date-type field into a string that meets your specifications. It is expressed like DATETIME_FORMAT(Datetime, 'format specifier'), meaning the format specifier can be something like 'DD-MM-YYYY,' 'YYYY/MM/DD,' 'MM.DD,' etc.
As an example, the formula DATETIME_FORMAT('10/22/2003', 'M') returns 10.

Supported DATETIME_FORMAT specifiers
Note
The format specifiers "w" and "W" behave differently. "W" is the "ISO week of year," while "w" is for the "locale week of year" (Gregorian calendar in GMT). 2/11/21 falls on the 6th ISO week and on the 7th Gregorian week. Airtable uses the Moment.js for date parsing.

Common formatting examples
ISO 8601 example:
ISO 8601 represents date and time in the year-month-day-hour-minutes-seconds-milliseconds format.
For example, 2025-12-31 15:00:00.000, represents the 10th of July 2020 at 3 p.m. It’s important to note that there is no time zone offset specified and the time is generally assumed to be in UTC format.
