Learning

Follow daily learning cycles and create personal Torah learning schedules with chosen coverage, pace and review.

See published daily learning beside Hebrew calendar dates. Build a personal plan by sefer, masechta or range, choose learning days and set daily, weekly and monthly review.

Save a plan to your account, export it as CSV, Excel or a printable PDF, and activate custom learning in the monthly calendar.

Jewish Cosmology is an interactive research and educational web application connecting Hebrew dates, traditional Jewish calendar calculations and halachic concepts of time with the observable motions of the Sun, Moon and planets, astronomical seasons and eclipses.

JavaScript is required for the interactive explorers and calculations. The descriptions and navigation remain available without JavaScript.
