Extension Datepicker

Core extension for date fields (field types “Date + time” and “Date + time, timezone-dependent”, single-line display – not for “Time”). Next to the text field it adds a calendar in the language and date format of the user and – depending on the setting – a time field. It is based on the library vanillajs-datepicker.

Always available, no installation needed. Unlike Calendar, it is not preselected automatically.

Settings per field

Setting	Default	Meaning
Picker	by field type	“by field type” and “date and time”: calendar and time field; “date only”: only the calendar
“Today” and “Clear” buttons	on	“Today” selects today's date, “Clear” empties the field
Show week numbers	off	column with the calendar weeks on the left of the calendar

Operation

• A click into the calendar field opens the calendar; a click on a day takes it over and closes the calendar.
• chevron_left and chevron_right go back or forward one month; a click on month and year in the header switches to the month, year and decade overview.
• The time field takes hours and minutes.
• Month names, weekdays and the first day of the week follow the locale of the user (personal settings, “Date and number format”); if a translation is missing, the calendar appears in English.

What is written into the field

The value appears in the text field the way the backend displays date values – in the user's medium date format, e.g. 26.09.2030, 14:30 (de_DE) or Sep 26, 2030, 2:30 PM (en_US). The time is only appended if it is not 00:00. Conversely, when opening, the calendar takes over a value in the display format or in international notation (2030-09-26 14:30) from the text field. The text field remains freely editable; changes there appear immediately in the calendar and time field.
