Eating before Jewish Festival Midday

As on Shabbat, don't fast on Jewish festivals (except Yom Kippur!) past halachic midday.
  • If you will not finish shacharit before halachic midday, you should eat or drink earlier in the day, even before you begin shacharit—water can be sufficient for this purpose.
  • If you will finish shacharit, but not musaf, by halachic midday:
    • Finish shacharit,
    • Make kiddush,
    • Eat some mezonot, and then
    • Return to say musaf.
