We can also count the holidays by looking at how often each weekday repeats across the 31 days. Since \( 31 = 4 \times 7 + 3 \), the month contains 4 complete weeks plus 3 extra days. In any such month, the weekdays that fall on the first 3 days of the month occur 5 times each, while every other weekday occurs exactly 4 times. Day 1 is a Wednesday, so days 2 and 3 are Thursday and Friday, meaning Wednesday, Thursday and Friday each occur 5 times, and all other weekdays, including Saturday and Sunday, occur exactly 4 times. So there are exactly 4 Sundays. For the Saturdays, since day 1 is Wednesday, the first Saturday is day 4, so the four Saturdays fall on days 4, 11, 18 and 25, making the second Saturday day 11. Total holidays = 4 Sundays + 1 second Saturday = 5. Let's test each option against this.
Counting which weekdays repeat 5 times versus 4 times in this 31-day month confirms 4 Sundays and 1 second Saturday, 5 holidays, and 26 working days.
Therefore, the correct answer is 26.
