### How many months does a Jewish year have?

### Why are lunar months a problem for lunar calendars?

A lunar calendar is based on lunar months (the cycle of the moon's phases takes 28 days). Since this cycle is fairly constant, the months all have the same length. The problem arises because no whole number of lunar months corresponds to one year; the closest is 13 months, equal to 364 days. This leaves an overhang of one and a quarter days each year which must be accounted for in a similar manner to…

### How many lunar months in a lunar year?

It depends. Some systems... for example, the Hebrew... sometimes have 12 months and sometimes have 13 months in an effort to keep the calendar more or less aligned with the seasons. In other systems, like that used by Islam, they basically say the heck with the seasons and use the same number of months in every year, so their calendar "drifts". In any system, the answer is almost certainly going to be either 12, or…

### What month is the 8th lunar month?

It depends on what calendar you're using. Also, lunar months don't line up with calendar months. In a lunisolar calendar like the Hebrew calendar, they make up for this by adding a thirteenth month every couple of years so most lunar months stay in approximately the same part of the year (so Hannukkah is always sometime around November-December); in a strictly lunar calendar like the Islamic calendar, any given lunar month can occur in literally…

### Why are there twelve months in a year?

A lunar cycle is about 29.5 days; the months in the Gregorian calendar have almost 30.5 days on average.

The idea of months began as "Moon Cycles"... and thus the term Months from the word Moon. A lunar month, however has 29.53 days, and a solar year has 365.242 days... So the seasons would shift slowly with calendars based on 12 lunar months (and you would still have either 29 of 30 day months to compensate for fractional days in the lunar cycles). But, perhaps because the moon (lunar) cycles were previously used, 12…

### Why are there not 13 months?

The "month" was originally invented in an attempt to split the year up into slices that match the moon's cycle of phases. In one year, the moon goes through its complete cycle of phases 12.368 times. That's closer to 12 than it is to 13. So, even though the system never really caught on, 12 months in a year still stay closer to paralleling the moon's changes than 13 shorter months would. To look at…
