Examples

Example 1

DateFormat(Date("2018-07-23"), "%B")

Evaluates the date value "2018-07-23" and returns the full month name, July.

Example 2

DateFormat([Date], "%a, %B %d, %Y")

Evaluates date values in the Date column and returns text strings formatted to include the abbreviated weekday name, full month name, two-digit day of the month, and four-digit year, with commas following the weekday name and day of the month.

In a column with Date and DateFormat, several dates in the format 'YYYY-MM-DD' are formatted to abbreviated weekday, full month, two-digit date, and four-digit year. For example, 2024-04-08 becomes Mon, April 08, 2024
