Hey, we missed Mother's Day in Israel
Different countries celebrate Mother's Day on various days of the year because the day has a number of different origins.
One school of thought[who?] claims this day emerged from a custom of mother worship in ancient Greece, which kept a festival to Cybele, a great mother of Greek gods. This festival was held around the Vernal Equinox around Asia Minor and eventually in Rome itself from the Ides of March (15 March) to 18 March.
The ancient Romans also had another holiday, Matronalia, that was dedicated to Juno, though mothers were usually given gifts on this day.
As for the date in Israel, it gives it as the 30th of Shvat. From the year I spent in Israel, I have absolutely no recollection of that date being anticipated with the same type of stuff that pops in stores in late April and May in the states. But, of course, I wasn't doing family shopping then.
