What is the Jewish celebration so they can remember moses when he escaped egypt?

Moses escaped Egypt as a fugitive, on his own. Roughly 40 years later, he led

a multitude of a few million or so Jews out of Egypt when Pharaoh, after much

fruitless coaxing, suddenly turned around and begged them to leave.

There was never any celebration to commemorate Moses' escape.

But the mass departure, known as the 'Exodus', has been commemorated

during the Jewish festival of Passover every year since it happened, and is

also recalled in Jewish prayer on every day of the year.
