Fascinating Zmanim and Calendar Calculations Which Shemoneh Esrei was last recited in the year 1994, and won’t be recited again until 2089? Why is it that some people’s nineteenth Hebrew birthday does not fall out on the same day as their civil birthday? On the night of his bar mitzvah, a boy flies from Australia to Los Angeles, where it is a day earlier. Does he become “un-bar mitzvah”? Is a person’s first yahrtzeit commemorated on the yom hamisah or the yom hakevurah? Why are seventeen pesukim in the Torah sometimes not read at all during the course of the year? When is the only time a klaf is rolled backward in the middle of the haftorah? In The Intriguing World of Jewish Time, you’ll find the answers to these questions and many others.
