A school is shut on Sundays, on 2nd Saturdays and on the holidays shaded orange. How many school days are there in the two months shown?

October 2027 (31 days): Sundays 3, 10, 17, 24, 31 (5); 2nd Saturday the 9th; orange holidays 2, 28, 29, 30 (none a Sunday or 2nd Saturday): 31 − 5 − 1 − 4 = 21. November 2027 (30 days): Sundays 7, 14, 21, 28 (4); 2nd Saturday the 13th; orange holidays 1 and 14, but the 14th is a Sunday already counted: 30 − 4 − 1 − 1 = 24. Total 21 + 24 = 45. (44 counts the Sunday holiday twice.)
