the gemara on 4b towards the bottom asks maybe the pasuk is used to include the 15th for burning. but how can you burn chametz on pesach?
yehoshua, ny
Dear Yehoshua,
To be exact, the Gemara asks that Hashboso (removing the Chametz) should be on the night of the 15th. First of all, only R' Yehuda requires burning- otherwise there are other ways . But if the Gemara now holds that this is the proper time then even burning is permitted and required to do, even though its Yomtov (just like we bring Korbanos on Shabbos)
All the best,
