The Gregorian calendar is a purely solar calendar, while the Jewish calendar is a solar-lunar calendar. In a bit more detail, the Gregorian calendar has months that have nothing to do with the moon and a leap day is added in February every few years to keep the days and months in their right season. In the Jewish calendar, every month starts with the new moon and a leap month is inserted (by doubling the spring month of Adar) when needed to keep the months in their right season.
It is a lunisolar calendar. The 12 months are based on the lunar cycle. each month begins with a new moon, and 7 times every 19 years an extra leap month is added.

I am a little confused regarding the beginning of the Hebrew year. I have read that it starts in the fall on Rosh Hashanah, and I have read that it starts in the spring on the 1st of Nisan.If the year begins on the first day of Rosh Hashanah, the third month is Kislev. But if Nisan is the first month then the third month is Sivan.Answer:The third month is Sivan. While the year starts in Tishrei, the months start in Nisan.
the Islamic calendar is a lunar calendar of of approx 355 days. Ramadan is an entire month of 28 to 30 days, depending when the new moon is sighted. Since we in the West follow a solar calendar of 365 .25 days, it stands to reason, the Islamic calendar month of Ramadan would fall ten days earlier every year. So it takes approx 30 years to make its way completely around the calendar and for about 3 years every 30, Christmas Day conincides with the month of Ramadan.
One disadvantage of a lunar calendar is that it does not align with the solar year, leading to discrepancies in season lengths. This can make it challenging for planning agricultural, religious, or cultural events. Additionally, leap years or intercalary months are often needed to compensate for the shorter lunar cycle, which can be complex to implement.
