January 2024 Current Affairs MCQs & Solutions

Explanation: 1949 years = 1600 + 300 + 49. Odd days = 0 + 1 + (12 × 2 + 37 × 1) = 1 + 61 = 62 = 6 odd days. Days in 1950 up to Jan 26 = 26 = 5 odd days. Total odd days = 6 + 5 = 11. 11 mod 7 = 4 odd days. Day 4 is Thursday.

Explanation: The years 2006, 2007, and 2009 are ordinary years (1 odd day each), and 2008 is a leap year (2 odd days). Total odd days between Jan 1, 2006, and Jan 1, 2010 = 1 + 1 + 2 + 1 = 5. Adding 5 days to Sunday gives Friday.

Explanation: An ordinary (non-leap) year has 365 days, which is exactly 52 weeks and 1 day. Because of this single extra day, the first and last days of any ordinary year fall on the exact same day of the week. Therefore, it will be Tuesday.

Explanation: A leap year has 366 days, equating to 52 weeks and 2 odd days. Because there is one more day than an ordinary year, the last day shifts one day forward from the first day. Thus, if the first day is Wednesday, the last day is Thursday.

Explanation: 2000 years have 0 odd days. The next 49 years consist of 12 leap years and 37 ordinary years. Odd days = (12 × 2) + 37 = 24 + 37 = 61. 61 mod 7 = 5 odd days. Add 1 day for Jan 1, 1950. Total = 6 odd days. The 6th day of the week is Saturday.

Explanation: December has 31 days. From 3rd Dec to 31st Dec there are 28 days. Then 3 days in January. Total days = 31. Dividing 31 by 7 leaves a remainder of 3 odd days. Sunday + 3 days = Wednesday.

Explanation: Days remaining in January = 31 - 20 = 11. Since it's a leap year, February has 29 days. Days in March up to the 20th = 20. Total days = 11 + 29 + 20 = 60. Dividing 60 by 7 gives 8 weeks and 4 odd days. Wednesday + 4 days = Sunday. Wait, Jan 20 is Wed. Days to Mar 20 = Jan(11) + Feb(29) + Mar(20) = 60. 60 % 7 = 4. Wed + 4 = Sunday. Let me correct the option.

Explanation: 1600 years have 0 odd days. The 300 years from 1600 to 1900 contribute 1 odd day. The year 1900 ends with 1 odd day overall relative to the century cycle. Thus, up to 1900, there is 1 odd day. Jan 1, 1901 adds 1 day. Total = 2 odd days. Day 2 of the week is Tuesday.

Explanation: 2016 is a leap year, containing 366 days. While an ordinary year starts and ends on the same day, a leap year ends exactly one day later than it started. Thus, if it begins on a Friday, it will end on a Saturday.

Explanation: By definition in the Gregorian calendar system, 1st January 1 A.D. is designated as a Monday. All odd day calculations historically use this as the absolute foundational starting point.

Explanation: In a leap year, February has 29 days (4 weeks and 1 day). If February 1st is a Sunday, it will have 5 Sundays. If January has 5 Sundays, it must end by Tuesday. So Feb 1 could be Wed, Thu, Fri. It cannot be Sunday. So max is 4. Let's re-read carefully. Can Feb have 5 Sundays? Yes, if Feb 1st is Sunday. But if Jan has 5 Sundays, Jan 1 is Sun, Mon or Tue. So Jan 31 is Tue, Wed or Thu. Feb 1 is Wed, Thu, Fri. Thus Feb CANNOT start on Sunday. Therefore, Feb must have exactly 4 Sundays. Let me fix the correct option to B.

Explanation: From Aug 15 to Jan 26: Aug(16) + Sep(30) + Oct(31) + Nov(30) + Dec(31) + Jan(26) = 164 days. 164 mod 7 = 3 odd days. Tuesday + 3 days = Friday. Wait, let me recalculate. Aug(16) -> 2. Sep(30) -> 2. Oct(31) -> 3. Nov(30) -> 2. Dec(31) -> 3. Jan(26) -> 5. Total = 2+2+3+2+3+5 = 17. 17 mod 7 = 3. Tue + 3 = Friday. I'll correct the option.

Explanation: 2008 is a leap year, so February has 29 days. Days = Jan (31 - 26 + 1 = 6) + Feb (29) + Mar (31) + Apr (30) + May (15) = 6 + 29 + 31 + 30 + 15 = 111 days.

Explanation: 1996 is a leap year, containing 366 days and exactly 2 odd days. Moving one full calendar year forward past February 29th adds these 2 odd days to the weekday. Monday + 2 days = Wednesday.

Explanation: The year 2000 was a century leap year, marking the end of a 400-year cycle which has exactly 0 odd days. Therefore, the very first day of the new cycle, January 1, 2001, naturally falls on a Monday.

Explanation: Calculate the odd days for the completed months: Jan (3) + Feb (0) + Mar (3) + Apr (2) + May (3). Total = 11 odd days. 11 mod 7 leaves a final remainder of exactly 4 odd days. Let me update the correct option to 4.

Explanation: The year 2007 is an ordinary year with 365 days, which translates to exactly 1 odd day. Thus, the same date in the subsequent year shifts forward by one day. Monday + 1 = Tuesday.

Explanation: Wait, 2024 is a leap year, but February 29th has already passed by November. Moving from Nov 2024 to Nov 2025 crosses February 2025, which has 28 days (ordinary year). This is 365 days, yielding 1 odd day. Wait, my option logic was Monday? Saturday + 1 = Sunday. Let me correct the options to have Sunday as correct.

Explanation: The interval from Jan 10, 2004, to Jan 10, 2005, incorporates the leap day of February 29, 2004. Therefore, the interval covers 366 days, equating to exactly 2 odd days. Tuesday + 2 days = Thursday.

Explanation: An ordinary year consists of 52 weeks plus 1 odd day. This odd day determines which weekday occurs 53 times instead of 52. If there are 53 Tuesdays, the year must absolutely begin on a Tuesday.
