Verse:Irta/Trician Jewish calendar

One Trician lunar month is 30.58122882574347 Trician days long; hence months in the lunar calendar usually have either 30 or 31 days. Twelve lunar months are about 366.97474590892164 days, which exceeds the solar year by 9.89409312183100 solar days. The Trician Jewish calendar is a lunisolar calendar and has the same month names as the Jewish calendar used on Earth/Irta, but it removes a month (Marcheshvan, since it doesn't have any major Jewish holidays? Any duties falling on Marcheshvan would be moved by a month) from 11 years per every 34-year period, to keep the months aligned with the solar year. Thus each 34-year cycle looks like this (x = a leap year, called shana mekhuseret?):

x - - x - - x - - x - - x - - x - - x - - x - - x - - x - - x - - -

(Passover falls on Nissan 15, which is required to be the first or the second full moon after the spring equinox which is on verteporfin 1 in the Talman solar calendar.)

Weekly Torah portions are also distributed slightly differently than on Earth.
