Retrieves calendar and clock information about the current locale.
Description
The Calendar and Clock functions are a set of functions that retrieve information about the current locale.
You can use these functions to display dates and times in the language of the current user. The single-column tables returned by Calendar and Clock functions can be used directly with the Items property of Dropdown and Listbox controls.
| Function | Description |
|---|---|
| Calendar.MonthsLong() | Single-column table containing the full names of each month, starting with "January". |
| Calendar.MonthsShort() | Single-column table containing the abbreviated names of each month, starting with "Jan" for January. |
| Calendar.WeekdaysLong() | Single-column table containing the full names of each weekday, starting with "Sunday". |
| Calendar.WeekdaysShort() | Single-column table containing the full names of each weekday, starting with "Sun" for Sunday. |
| Clock.AmPm() | Single-column table containing the long uppercase "AM" and "PM" designations. If the language uses a 24-hour clock, the table will be empty. |
| Clock.AmPmShort() | Single-column table containing the short uppercase "A" and "P" designations. If the language uses a 24-hour clock, the table will be empty. |
| Clock.IsClock24() | Boolean indicating if a 24-hour clock is used in this locale. |
Use the Text function to format date and time values using this same information. The Language function returns the current language and region code.
