May 24 will now be the last day for students, and May 31 will be the final day for teachers.
Tupelo previously added Feb. 18, Feb. 21, April 25 and May 23 to replace its other snow days.
The district has also canceled its early release days scheduled for Feb. 23 and March 9 in order to increase instruction time for students. The district has three early release days remaining: March 30, April 13 and May 16.
Those afternoons will be used for training for teachers.
