The Gilaki or Deylami calendar of Gilan, whose year begins on 17 Mordad with Nowruzbal, is kept today on fixed Jalali days. Its month of Tir ma runs from 15 Aban to 14 Azar, so the 13th of Tir, the day of Tirgan, falls on 27 Aban, and Gilanis keep 27 Aban as Tirgan by their own calendar. In eastern Gilan Tirgan was also kept, as in Mazandaran, on the Tabari date, the night of 12 Aban (Tirma Sizzeh Shu).
