Aptitude Questions on Calendar and Clocks
Q. 1 “January 1, 2025” is a Wednesday. Fast forward an entire year, what day of the week will greet the new year on “January 1, 2026”?
A) Thursday
B) Friday
C) Saturday
D) Sunday
Check Solution
Ans: A) Thursday
2025 is not a leap year, so it has 365 days. Hence, January 1, 2026, will be 365 days later, which is $365 \div 7 = 52$ weeks and 1 extra day.
So, the day will shift by 1 day: Wednesday + 1 = Thursday.
Q. 2 How many odd days are there in 1200 years?
A) 0
B) 1
C) 2
D) 3
Check Solution
Ans: A) 0
For 1200 years:
- 800 years (leap years) contribute (800÷4=200×2)=400(800 \div 4 = 200 \times 2) = 400(800÷4=200×2)=400 odd days.
- 400 years contribute 0 odd days (as the Gregorian cycle repeats).
Thus, $400 + 0 = 400 \div 7 = 0$ odd days.
Q. 3 Which of the following years is not a leap year?
A) 1900
B) 2000
C) 1600
D) 2400
Check Solution
Ans: A) 1900
A year is a leap year if:
- Divisible by 4.
- Not divisible by 100, unless divisible by 400.
1900 is divisible by 100 but not by 400, so it is not a leap year.
Q. 4 Picture a clock displaying the time 4:20. If you could freeze time and measure the angle formed between the hour hand and the minute hand, what would that angle be?
A) 10°
B) 20°
C) 30°
D) 40°
Check Solution
Ans: A) 10°
At 4:20:
- Hour hand’s position: $4 \times 30 + \frac{20}{60} \times 30 = 120 + 10 = 130°$.
- Minute hand’s position: $20 \times 6 = 120°$
Angle = 130°−120°=10°.
Q. 5 How many days are there between March 3, 2022, and March 3, 2023 (non-leap year)?
A) 365
B) 364
C) 366
D) 367
Check Solution
Ans: A) 365
2022 is not a leap year. From March 3, 2022, to March 3, 2023, there are 365 days.
Q. 6 Calendars repeat themselves every few years. Which of the following years will have the same calendar as 2024?
A) 2030
B) 2052
C) 2056
D) 2060
Check Solution
Ans: B) 2052
Leap years repeat every 28 years. Thus, 2024 + 28 = 2052.
Q. 7 How many times in a day do the hour and minute hands coincide?
A) 11
B) 12
C) 22
D) 24
Check Solution
Ans: C) 22
The hour and minute hands coincide once every hour, except at 12 o’clock. In a 12-hour cycle, this happens 11 times. Over 24 hours: $11 \times 2 = 22$
Q. 8 Think back to the dawn of the 21st century. When January 1, 2001, ushered in the new millennium, what day of the week did the world wake up to?
A) Monday
B) Tuesday
C) Wednesday
D) Sunday
Check Solution
Ans: A) Monday
January 1, 2000, is Saturday (given). 2000 is a leap year.
So, January 1, 2001 = Saturday+2=Monday
Q. 9 If a clock shows 8:40, what will the time be in the mirror reflection?
A) 3:20
B) 4:20
C) 5:20
D) 3:40
Check Solution
Ans: A) 3:20
The time in the mirror = 12:00−8:40 = 3:20
Q. 10 If today is Sunday, what day will it be after 100 days?
D) Friday
