Calendar Questions Trick
To solve Calendar Reasoning Questions quickly, use these tricks:
- Odd Days Concept: Divide the number of days by 7. The remainder (odd days) determines the day shift (e.g., 1 odd day = 1 day forward).
- Leap Year Check: A year divisible by 4 is a leap year (except century years, which must be divisible by 400). Leap years have 2 odd days; others have 1.
- Month Codes: Memorize codes for months (e.g., January: 1, February: 4, March: 4, etc.) to calculate days faster.
- Reference Date: Use a known date (e.g., January 1, 2000, was Saturday) to calculate other dates by adding odd days.
- Century Code: For dates in different centuries, use codes (e.g., 1900s: 0, 2000s: 6) to adjust calculations.

Calendar Reasoning Formula
Key Calendar Reasoning Formulas to solve questions efficiently:
- Odd Days: Number of days ÷ 7 = Quotient + Remainder (odd days). Odd days determine day shift (e.g., 3 odd days = 3 days forward).
- Leap Year: Year ÷ 4 = Integer (except centuries, which need ÷ 400). Leap year = 366 days (2 odd days), Non-leap = 365 days (1 odd day).
- Day of the Week: (Year Code + Month Code + Date + Century Code) ÷ 7. Remainder gives day (0 = Sunday, 1 = Monday, ..., 6 = Saturday).
- Year Code: (Year + Year/4) mod 7 (last two digits of year).
- Month Codes: January: 1, February: 4, March: 4, April: 0, May: 2, June: 5, July: 0, August: 3, September: 6, October: 1, November: 4, December: 6 (adjust for leap years: January: 0, February: 3).
- Century Codes: 1600s: 6, 1700s: 4, 1800s: 2, 1900s: 0, 2000s: 6, 2100s: 4.
Memorize these formulas and practice applying them to save time.
Solutions to Calendar Reasoning Questions
| Question No. | Answer | Explanation |
|---|---|---|
| 1 | A) Saturday | January 1, 2000, is a known reference: Saturday (2000 is leap year, century code 6). |
| 2 | D) Friday | March 15, 2020, to April 10, 2020: 16 days (March) + 10 days (April) = 26 days. 26 ÷ 7 = 3 remainder 5. Sunday + 5 = Friday. |
| 3 | A) Yes | 2024 ÷ 4 = 606 (integer). 2024 is a leap year. |
| 4 | A) Sunday | 2004 is a leap year. Use formula: Year code (04 + 04/4 = 5), Month code (Feb: 3), Date (29), Century code (6). Total = 5 + 3 + 29 + 6 = 43 ÷ 7 = 1 (Sunday). |
| 5 | B) 75 | June (30 days) + July (31 days) + August 1–15 (15 days) = 30 + 31 + 15 = 76. Exclude June 1: 76 - 1 = 75 days. |
| 6 | A) Monday | 2010 to 2011: 2010 is non-leap (1 odd day). Sunday + 1 = Monday. |
| 7 | B) Monday | Year code (95 + 95/4 = 118 ÷ 7 = 6), Month code (Dec: 6), Date (25), Century code (0). Total = 6 + 6 + 25 + 0 = 37 ÷ 7 = 2 (Monday). |
| 8 | C) Thursday | 2025 is non-leap (1 odd day). Wednesday + 1 = Thursday. |
| 9 | B) 5 | Leap years (divisible by 4): 2000, 2004, 2008, 2012, 2016, 2020. Count: 5 (2000 included, 2020 excluded). |
| 10 | A) Sunday | 2018 to 2019: 2018 is non-leap (1 odd day). Saturday + 1 = Sunday. |
