You can wish someone “Happy Hanukkah” any time during the holiday itself, and a little bit before is also fine in many settings. The key is to use it when Hanukkah is actually approaching or being observed, rather than at a random time of year.
During the holiday
Hanukkah lasts for eight nights, and it is completely appropriate to say “Happy Hanukkah” on any of those days or nights. Many people will say it when the holiday begins and keep using it throughout all eight days.
Just before it starts
It is also common to offer Hanukkah wishes in the days leading up to the start of the holiday, especially in cards, emails, or general seasonal greetings. This works well if you may not see the person during the actual days of Hanukkah.
Phrases you can use
- “Happy Hanukkah!” is always correct and widely understood.
