5.5.2.2 Calendar System Date Conversion ¶
Calendar supports conversion of dates from Gregorian (default) to a number of different calendar systems. Choose “(c) Conversions›” from the main menu to select from a list of such calendars.
Supported calendar systems:
- Astronomical (
casual-calendar-astro-tmenu) - Bahá’í (
casual-calendar-bahai-tmenu) - Ethiopic (
casual-calendar-ethiopic-tmenu) - French Revolutionary (
casual-calendar-french-tmenu) - Hebrew (
casual-calendar-hebrew-tmenu) - Islamic (
casual-calendar-islamic-tmenu) - Julian (
casual-calendar-julian-tmenu) - Lunar (Chinese) (
casual-calendar-lunar-tmenu) - Mayan (
casual-calendar-mayan-tmenu) - Persian (
casual-calendar-persian-tmenu)
Selecting a calendar system will raise a menu that offers date conversion commands between it and the Gregorian system. In the screenshot below, the Lunar (Chinese) calendar system menu is shown.
To convert a Gregorian date to Lunar (Chinese):
- Move cursor (point) in Calendar window to desired date. (The command “(g) Goto…” can be used to accomplish this.)
- Choose “(c) Date at Cursor”.
To convert a Lunar (Chinese) date to Gregorian:
- Choose “(G) Goto…” and follow the prompts.
Certain non-Gregorian calendar systems are supported by the diary (Bahá’í, Hebrew, Islamic, Lunar (Chinese)). For such systems, their menus will offer choices to insert diary events.
Note that inserting non-Gregorian diary events require configuration of the variables diary-nongregorian-listing-hook and diary-nongregorian-marking-hook as detailed in Diary Entries using non-Gregorian Calendars ((emacs)Non-Gregorian Diary).
Both of these variables can be configured from the Calendar Settings menu.
