It is Jewish custom to bless children each Shabbat and on every festival holiday. The customary blessing that parents bestow on their children on Shabbat and holidays is specific to boys and girls.
Whenever I'm asked if the Jewish holidays are coming early or late this year, I promptly answer that they'll be coming on time. And that's partially true. Rosh Hashanah will always arrive on the first day of the Jewish month of Tishrei just as Hanukkah will always begin on the 25th of Kislev.
