Judaism and Islam, which both observe a lunar calendar, treat this disparity differently, explaining why it is so noteworthy that this year, the Muslim holy month of Ramadan begins on the same day as the Jewish new year, Rosh Hashana (Oct. 4).

Can someone tell me why this is so noteworthy? Frankly who gives a rats rear end that the holidays happen to start on the same day this year?

Most lunar calendars have intercalary months (an additional month added every second or third year) in order to keep the lunar calendar in line with the seasons. For people living in an agricultural society, this would be for a practical reason, so that harvest festivals happen at harvest-time and so on. Muhammad decided to forbid intercalary months, so the Muslim year gains a year on the solar calendar about once every 33 years.
