On Lag BaOmer, there’s no specific prayer or phrase you have to say, but there are a few things people might say or talk about depending on how they celebrate:

Casual greetings:

• “Chag Sameach!” – This just means “Happy Holiday!” and works for pretty much any Jewish holiday.

• “Lag Sameach!” – A more specific twist people might use just for this day.

What people talk about:

• “It’s the yahrzeit (anniversary of death) of Rabbi Shimon bar Yochai today.”

• “We’re halfway through the Omer!” – Since it’s the 33rd day out of 49.

• “The bonfires are tonight!” – If you’re in Israel or a community that lights them, this is a big deal.

More religious or traditional settings:

In more observant circles, you might hear or say blessings or Psalms (Tehillim), especially at the tomb of Rabbi Shimon bar Yochai in Meron, Israel — but it’s more about celebration than formal synagogue liturgy.

So yeah, there’s no fixed thing you have to say — it’s more about the vibe: bonfires, music, good food, and remembering a great teacher.
