what is the start of the jewish calendar
Hebrew calendar The Jewish New Year (Rosh Hashanah) is a two-day public holiday in Israel. However, since the 1980s an increasing number of secular Israelis celebrate the Gregorian New Year (usually known as "Silvester Night"—"ליל סילבסטר") on the night between 31 December and 1 January. Prominent rabbis have on several occasions sharply denounced this practice, but with no noticeable effect on the secularist celebrants.[79]
Week A continuous seven-day cycle that runs throughout history paying no attention whatsoever to the phases of the moon was probably first practiced in Judaism, dated to the 6th century BC at the latest.[7][8]
Gregorian calendar The Gregorian calendar is internationally the most widely used civil calendar.[1][2][Note 1] It is named after Pope Gregory XIII, who introduced it in October 1582.
Indian national calendar Usage started officially at 1 Chaitra 1879, Saka Era, or 22 March 1957. However, government officials seem to largely ignore the New Year's Day of this calendar in favour of the religious calendar.[3]
