why does the holiday 'Yom Kippur' jump all over the calender?

Question

this year it was in october. next year it's in september.

Answer 1

The same reason Easter jumps all over the calendar--sometimes it is in April--sometimes March, etc. It is because it based on a different (older) calendar that measures the year differently than the current Gregorian calendar we use now. So, when the old calendar matches up with the new calendar, the dates do not correlate in the same way.

Answer 2

It's because the Jewish calendar is based on astronomical observations regarding both the sun and moon (Jewish months start with the New Moon, and the lunar cycle is about 29.5 days).

There are lots of rules & stuff for calculating the Jewish calendar,to try and synchronize the solar and lunar cycles. There's also lots of variation in what constitutes a year in that calendar (it could be 353, 354, 355, 383, 384, or 385 days), The link below has good info about this.

Since Yom Kippur falls a set number of days after Rosh HaShanah (the first day of the year), and that first day of the year can vary as explained above, the holiday jumps around.

Answer 3

The Jewish Calendar is a lunar-solar calendar. The months are based on the moon and the year is based on both the moon and the sun. Therefore, most non-leap years on the Jewish calendar have 354 days. There are 7 leap years every 19 years and in those years a 29 day month is added to the calendar in late winter/early spring. Those years typically have 383 days. Additionally, a day here and there are added or subtracted to maintain synchronicity with the solar year. Thus every 19 years, the Jewish and secular calendars count off the identical number of days.

Answer 4

It is dependant on the lunar calander, which is eleven days shorter than the solar one, so it will be 11 days earlier each year. But 7 out of 19 years, an extra 30-day month is added, making it 19 days later. There are slight adjustments of one day also made, following a complex rule system. In short: it has to be about 10 days after the New Moon, which changes.

Answer 5

It is according to the Hebrew calendar. Easter is calculated differently, Easter falls on the first Sunday after the first full moon after the first day of spring.

Answer 6

The Jewish calender is based upon the phases of the moon, which is why Easter is different every year. Easter is different every year because Passover is different and the scheduling of Easter is based upon the first full moon following Passover.

Answer 7

yom kippur is always on the same day... the 10th of tishri.

its because jews use a different calendar. it falls on the same day every year of OUR calendar, but not on the same day of the rest of the world's calendar.

Answer 8

because the jewish calender is way different than ours is. different months and all that. its the same reason Hannukah can be after Christmas one year and another be in late November. They're in the year 4000 something or other and all that, sorry i dont know the exact months and numbers.

Answer 9

Kinda like Easter is different every year....has something to do with the moon phases I think

Answer 10

The Jewish Calendar is not the same as the one we use.
