The Chag HaMatzot in 2024 is April 23 through 29, in the sundown of the 23rd until the sundown of the 30th.
On the Hebrew calendar this seven-day festival is from the 15th day of the first month to the 21st (Leviticus 23:6). The first and last days of the Feast of Unleavened Bread are sanctified days, days to rest from work and attend “a set-apart convocation” or worship service (verses 7-8).
