If an Independence Day (15th August) was celebrated on a Tuesday in a non-leap year, on what day will the next Republic Day (26th January) fall?
Answer:
Friday
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.
2282
Which of the following dates is impossible?
Answer:
29th February 1800
1800 is a century year. According to leap year rules, century years must be divisible by 400 to be leap years. Since 1800 is not divisible by 400, it is an ordinary year with only 28 days in February.
2283
If 1st May of a year is Tuesday, what day is 1st June of the same year?
Answer:
Friday
May has 31 days. The number of odd days in May is 31 mod 7 = 3. Moving from 1st May to 1st June adds these 3 odd days to the current day. Tuesday + 3 days = Friday.
2284
In a leap year, if January has 5 Sundays, what is the maximum number of Sundays February can have?
Answer:
4
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.
2285
If a month has 28 days and starts on a Monday, how many Mondays does it have?
Answer:
4
A 28-day month consists of exactly 4 full weeks (28 / 7 = 4). Because there are no remainder days, every single day of the week from Monday to Sunday appears exactly 4 times in that month.
2286
What is the day of the week on 1st January 1 A.D.?
Answer:
Monday
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.
2287
A century year is a leap year only if it is divisible by:
Answer:
400
The Gregorian calendar dictates that a year ending in '00' is only considered a leap year if it is perfectly divisible by 400. This corrects the slight overestimation caused by adding a leap day every 4 years.
2288
If the first day of an ordinary year is Friday, the last day is:
Answer:
Friday
An ordinary year comprises 52 full weeks and 1 extra day. Because of this structural alignment, the first day of the year (January 1st) and the last day of the year (December 31st) are always exactly the same day of the week.
2289
The calendar of 1971 used exactly again in which year?
Answer:
1982
1971 is a (Leap Year + 3) since 1968 was a leap year. Years formatted as LY+3 typically repeat after 11 years. Thus, 1971 + 11 = 1982.
2290
If 10th April falls 2 days before Friday, what day will be the 25th of that month?
Answer:
Thursday
Two days before Friday is Wednesday, meaning the 10th is Wednesday. The difference is 25 - 10 = 15 days. Since 15 is a multiple of 7 plus 1 (14 + 1), we add 1 odd day. Wednesday + 1 day = Thursday.
