DateFormat
The DateFormat function evaluates a date value and extracts datetime components (as text strings) in the specified format.
Syntax
DateFormat(date, format)
Function arguments:
| date | (required) The date or column of date values to evaluate. |
| format | (required) The datetime components (as a datetime format string) to extract. |
Compatible format specifiers
The DateFormat function uses the datetime formatting functionality of the connected data platform (see Notes). The following format specifiers are supported by most connections and can be used to build the datetime format string.
| Format | Description | Example output (for 2018-07-08 00:34:59) |
|---|---|---|
| %Y | Four-digit year | 2018 |
| %y | Two-digit year | 18 |
| %q | Quarter of the year (1–4) | 3 |
| %m | Two-digit month | 07 |
| %B | Full month name | July |
| %b | Abbreviated month name | Jul |
| %A | Full day of week | Sunday |
| %a | Abbreviated day of week | Sun |
| %d | Two-digit day of month (01-31) | 08 |
| %H | Two-digit hour based on 24-hour clock (00–23) | 00 |
| %I | Two-digit hour based on 12-hour clock (01–12) | 12 |
| %M | Two-digit minutes (00–59) | 34 |
| %S | Two-digit seconds (00–59) | 59 |
| %p | AM or PM | AM |
| %L | Three-digit milliseconds (000–999) | 000 |
| %f | Six-digit microseconds (000000–999999) | 000000 |
| %Z | Time zone offset | -07:00 |
| %% | Percent symbol | % |
Notes
- DateFormat can only output formats that are supported by your connected data platform. For example, passing
%Ato the format argument typically returns the full day of the week (e.g.Sunday,Monday). However, on Snowflake connections, this will return the abbreviated day of week format (e.g.Sun,Mon) equivalent to%a. This is because Snowflake does not support a full day of week.
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.
