What is the difference between the Jewish calendar and the Gregorian calendar?

Answer 1

The Jewish calendar is based on both the moon and the sun. A month can have 29 or 30 days (to start each month with a new moon), and there can be 12 or 13 months to a year. In every 19 years, 12 of the 19 years have 12 months, while seven have 13 months, thus keeping in line with the solar calendar and making every 19 years on a Jewish calendar exactly equal to 19 years on the Gregorian calendar.

Answer 1

The Hebrew months have a rough correspondence to the Gregorian calendar. They line up with Gregorian months in a general way.

Answer 2

The Hebrew calendar is a lunisolar calendar which means that there is a general correspondence between the Hebrew months and the seasons, and there is a nearly exact correspondence between the Hebrew dates and the phases of the moon. This is as opposed to the Gregorian calender which is a solar calendar and has an almost exact correspondence between its months and the seasons (but no correspondence with the phases of the moon). As a result, while the Hebrew month of Nissan will dance around (from the Gregorian perspective) between March and April, it will never be in August or November or February. This is in contrast to the Islamic Calendar which is purely lunar and where the months dance around the solar year. For example, Ramadan is currently (in 2013) a summer month. In 2030, it will be a winter month, etc.

Additionally, because of the way the Hebrew calendar accounts for its lunisolar discrepancies and the because of the way that the Gregorian Calendar accounts for its discrepancies, the Hebrew Calendar and the Gregorian Calendar date will be the same (or only one day off) for every date nineteen years apart. For example: August 25, 1994 was 18 Elul 5754 and August 25, 2013 (19 years later) will be 19 Elul 5773 (19 years later).

Answer 3

The Jewish calendar consists of twelve lunar months. It also keeps in step with the solar year, by adding a thirteenth lunar leap-month seven times every nineteen years. The Gregorian calendar, which sticks to the solar year, ignores the lunar months and does not attempt to keep in step with them.
