On Yom Kippur, the most appropriate and traditional greetings to say to someone include:
- "Gmar Chatima Tovah" (גמר חתימה טובה), meaning "a good final sealing," reflecting the wish that the person's fate be sealed for goodness in the Book of Life at the end of Yom Kippur.
- "Tzom Kal" (צום קל), meaning "an easy fast," acknowledging the difficulty of the fasting day.
- In English, you can say "Have a meaningful fast," "Wishing you a meaningful Yom Kippur," or "May you be sealed for goodness in the Book of Life."
- It is generally not customary to say "Happy Yom Kippur" because the day is solemn and reflective, not celebratory.
These greetings are respectful and thoughtful ways to acknowledge the significance of Yom Kippur to someone observing it.
