The Jewish Calendar 2025

Jewish festivals are celebrated on dates which are determined according to a lunar calendar which does not synchronise with the solar calendar. In order to ensure that seasonal festivals, such as celebrations of harvests, fall in the correct season, the calendar is adjusted.

Seven times in every nineteen years, we add an extra month to the year. How do we do this? When we reach the last month of the year, Adar, we just repeat it! The Jewish day begins at sunset, which means that all Jewish festivals begin in the evening before the festival day, rather than beginning immediately after midnight. This reflects the origin of the festivals in times when there were no clocks. At least everyone knew when it was dark or light. So a day ended (and the next one began) when the sun set.
