The Jewish calendar has 12 months. They are Tishre, Chesvan, Kislev, Tevet, Shevat, Adar, Nissan, Iyar, Sivan, Tamuz, Av, Elul. However, during a leap year, an extra month is added. So during a leap you you have Adar I and Adar II which gives you 13 during a leap year.
A leap year is special because it has one extra day, February 29th, which is added to keep our calendar in alignment with the Earth's orbit around the sun. Without this extra day, our calendar would gradually fall out of sync with the solar year. Leap years occur every four years, except for years that are divisible by 100 but not divisible by 400.

The extra 14 days combined with an additional day added to the calendar is associated with the transition from the Julian calendar to the Gregorian calendar. This adjustment was made to correct inaccuracies in the Julian system, which miscalculated the solar year. The term for this adjustment is often referred to as a "calendar reform," and the extra day added in a leap year is simply known as "Leap Day."
No, a leap year does not affect the biological processes of conception or pregnancy. The likelihood of getting pregnant is influenced by factors such as ovulation timing, overall health, and reproductive conditions, rather than the calendar year. Leap years simply add an extra day to the calendar and have no impact on fertility.
Because of the extra weekday each year, and because of leap years, identical non-leap year calendars repeat on a cycle of 6 or 11 years. Leap years repeat every 28 years. (There are only 14 different possible calendars.) The years that were the same calendar as 2012 were 1984, 1956, and 1928.
A leap year is a year containing one extra day in order to keep the calendar year synchronized with the astronomical or seasonal year. For example, in the Gregorian calendar (common calendar), February in a leap year has 29 days instead of the usual 28, so the year lasts 366 days instead of the usual 365.
It doesn't. It has 354 days because the months are lunar. But an extra leap month is sometimes added.
Because 1500 is a century , so we should check whether it is divisible by 400 not by 4 alone. Since it is not divisible by 400 its not a leap year.1500 WAS actually a leap year, the Gregorian calendar didn't commence until the year 1600.
By having a leap year every four years.
Yes. If we did not insert the leap day during leap year, the calendar date of the equinoxes and solstices would change and eventually come at very different times in the calendar year. The whole purpose of Leap Year/Leap Day is to keep our calendar aligned with the equinoxes, solstices, and seasons in general.
In 46 BC with the creation of the Julian calendar.
