Question

If January 1 is a Friday, what is the first day of the month of March in a leap year?

• A. Wednesday
• B. Thursday
• C. Tuesday
• D. Friday

Hint:

Remember leap year February has 29 days.
Calculate days passed and use modulo 7 to find the weekday.

Answer 1

The Correct Option is C

Step 1: Days in January and February in a leap year
- January has 31 days
- February has 29 days (leap year)
Step 2: Calculate total days passed before March 1
Total days = 31 (Jan) + 29 (Feb) = 60 days
Step 3: Calculate day of March 1
- Days passed modulo 7: $60 \mod 7 = 4$ days
- Since Jan 1 is Friday, add 4 days: Friday → Saturday (1), Sunday (2), Monday (3), Tuesday (4)
Therefore, March 1 falls on Tuesday.
