During antiquity the lunar calendar that best approximated a solar-year calendar was based on a 19-year period, with 7 of these 19 years having 13 months. In all, the period contained 235 months. Still using the lunation value of 291/2 days, this made a total of 6,9321/2 days, while 19 solar years added up to 6,939.7 days, a difference of just one week per period and about five weeks per century.

Even the 19-year period required adjustment, but it became the basis of the calendars of the ancient Chinese, Babylonians, Greeks, and Jews. This same calendar was also used by the Arabs, but Muhammad later forbade shifting from 12 months to 13 months, so that the Islamic calendar, even today, has a lunar year of 354 days. As a result, the months of the Islamic calendar, as well as the Islamic religious festivals, migrate through all the seasons of the year.

How come and or why is the day of Atonement not celebrated on July 10th?

The calendar used in the Old Testament days was not like the calendar we use now.

In those days, the Israelites used a calendar based on the lunar cycle, with adjustments to help the calendar match the progress of the earth around the sun.

"In the times of the Old Testament, they used the Jewish Calendar. The months were Nisan, Ijar, Siwan, Tammus, Ab, Elul, Tishri, Margeswan, Kislef, Tebet, Sebat and Adar (in that order). It is a lunar calendar, and some of the months have 29 days, and other have 30 days. Each month starts when it is full moon in Jerusalem. Yet the actual lunar cycle is only about 29 ½ days, which resulted in a year of only 354 ½ days. Keeping the lunar calendar coordinated with the seasons of the year required adding a 13th month to the lunar calendar seven out of every nineteen years. This additional month was added to the end of the year following the last month Adar, and was simply called Second Adar.

Today we use a calendar based on the position of the earth around the sun, a solar calendar rather then a lunar one.

But the Day of Atonement is still held on the correct date according to the original Old Testament calendar. That's why it changes from year to year, like Easter -- because their dates are calculated on the lunar cycle rather than the solar cycle (like Christmas.)

Why don't the twelve months all have the same number of days?

Our calendar is based on the old Roman Calendar consisting of ten months of 30 days each. Augustus was advised that the calendar was off, and needed two more months--he added one for himself, and one for his uncle Julius. Later it was found to be still off, and days were deducted from February to augment several other months. The Church (at that time there was only one) realized that the months were slipping off schedule at the rate of one day about every 4 years. On the fourth year, a day was added to February to 'leap forward' and catch up to the seasons. One more major adjustment in the early Middle Ages, and the calendar was ready to fly. B.
