LeapVariant

LeapVariant[n]

represents a repeated calendar element caused by a leap period.

Details

  • LeapVariant is typically used in lunisolar calendars, where the lunar cycles of months or days need to be periodically adjusted to maintain alignment with the solar cycles of other calendar elements.
  • Calendars that use LeapVariant elements maintain sequentially numbered calendar elements (such as months or days), and the LeapVariant element is used to insert a repeated element before or after a given number in that sequence (e.g. months sequenced as 1, 2, 3, 4, LeapVariant[4], 5, 6, 7, 8, 9, 10, 11 and 12).
