You generally do not say “Happy Yom Kippur,” because it is a solemn day of fasting, reflection, and atonement rather than a festive celebration.

What to Say Instead

  • “Have an easy fast.”
    This is the most common and widely accepted English greeting, since most observant Jews fast on Yom Kippur.
  • “Wishing you a meaningful fast” / “Wishing you a meaningful Yom Kippur.”
    This respects the reflective, spiritual nature of the day.
  • “G’mar chatima tovah” (or “Gmar tov” for short)
    A traditional Hebrew phrase meaning “May you be sealed for good” or “A good final sealing,” referring to being inscribed in the Book of Life.
  • “Tzom kal”
    Hebrew for “Have an easy fast.”
  • “Gut yontiff” / “Yom tov”
    Yiddish/Hebrew phrases meaning “good holy day,” used by many observant communities.

How to Choose the Right Greeting

  • If you are not sure how religious they are , a safe option is:
    • “Wishing you a meaningful fast”
    • “Wishing you a meaningful Yom Kippur”
  • If you know they are fasting , you can say:
    • “Have an easy fast” or “Tzom kal.”
  • If they are more traditional/observant , using Hebrew phrases like “G’mar chatima tovah” or “Gmar tov” may feel especially appropriate and appreciated.

Sample Messages You Can Use

  • “Wishing you a meaningful Yom Kippur.”
  • “Have an easy and meaningful fast.”
  • “G’mar chatima tovah — may you be sealed for good this year.”
  • “Tzom kal, thinking of you today.”
