ARTIKEL SEINDONESIA

This module is rated as beta, and is ready for widespread use. It is still new and should be used with some caution to ensure the results are as expected.

Usage

For templates, you might want to use {{Date period}} instead.

{{#invoke:Date period|_main|dateA|dateB}}

Automatically formats two given dates with a space and and en dash. Dates can be of any format supported by Module:Date.

If the month is the same, it is only shown once. If the month and day is the same, it will not show a second part at all. If the year is different, it will show the year unless disabled.

Date A	Date B	Output
2021-02-19	present	February 19 – present
present	2021-02-25	present – February 25
2021-02-19	2021-02-25	February 19 – 25
2021-02-19	2021-03-25	February 19 – March 25
2020-02-19	2021-02-25	February 19, 2020 – February 25, 2021

The year can be forcefully shown with the force-year parameter (third parameter of p._main).

Date A	Date B	force-year	Output
2021-02-19	2021-02-25	no	February 19 – 25
2021-02-19	2021-02-25	yes	February 19 – 25, 2021
2020-02-19	2021-02-25	no	February 19 – February 25
2020-02-19	2021-02-25	yes	February 19, 2020 – February 25, 2021

If one of the dates is invalid, the raw text will be displayed instead.

Date A	Date B	Output
2021-02-19	Sometime far in the future.	February 19 – Sometime far in the future.
Long ago	2021-02-25	Long ago – February 25
