The Mongolian Calendar holiday recurrence rule type is for holidays based on either the Mongolian lunar calendar or the Mongolian solar calendar, both of which share the same structure, albeit with different date offsets, as the Tibetan calendars and Bhutanese calendars.
➢At the time of writing (May 2021), all Mongolian calendar public holidays are lunar.
The structure of Mongolian lunar calendar holidays is a month-day pair with the option of observing the holiday on the leap month and/or leap day (if applicable).
