Which of the following months in a non-leap year have the exact same number of days and identical starting days?
Answer:
None of the above
In an ordinary year, April has 30 days and July has 31. But do they start on the same day? April to July = Apr(2) + May(3) + Jun(2) = 7 = 0 odd days. So they start on the same day, but don't have the same number of days. Wait, the question asks 'same number of days AND identical starting days'. This is impossible for Apr/Jul. Let's re-evaluate. Sept and Dec: Sep(2) + Oct(3) + Nov(2) = 7. September and December start on the same day, but Sep has 30, Dec has 31. Thus, Option D is the correct mathematical answer.

What is the day on 10th May 1857?
Answer:
Sunday
1856 years = 1600(0) + 200(3) + 56(14 LY + 42 NY = 28+42=70 = 0 odd). Total up to 1856 = 3 odd days. 1857 is NY. Jan to May 10 = 3+0+3+2+10 = 18 = 4 odd days. Total = 3+4 = 7 = 0 odd days. Day 0 is Sunday.
2253
How many days are in a month that starts on a Tuesday and has exactly 5 Tuesdays and 5 Wednesdays, but only 4 Thursdays?
Answer:
30
For a month to have exactly 5 occurrences of only the first two days of its week, it must consist of exactly 4 full weeks plus 2 extra days. Thus, the month has 28 + 2 = 30 days.
2254
A boy observed that his birthday in 2021 fell on a Wednesday. When will his birthday fall on a Wednesday again?
Answer:
2027
2021 is LY+1. Years that are 1 year after a leap year generally repeat their calendar after 6 years. So, his birthday will align identically on Wednesday in the year 2021 + 6 = 2027.
2255
If 1st January 2007 was Monday, what day of the week lies on 1st January 2008?
Answer:
Tuesday
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.
2256
If today is Wednesday, what day will it be after 85 days?
Answer:
Thursday
We find the odd days by calculating 85 mod 7. Since 84 is a multiple of 7 (12 weeks exactly), the remainder is 1. Adding 1 day to Wednesday gives Thursday.
2257
If 2nd October 2005 was Sunday, what day was 2nd October 2006?
Answer:
Monday
Although 2006 is not a leap year, the period crosses a standard 365-day interval. 365 days yield exactly 1 odd day. Moving forward 1 day from Sunday results in Monday.
2258
The calendar for 1988 repeats exactly in which year?
Answer:
2016
1988 is a leap year because it is divisible by 4. The entire calendar for any standard leap year replicates itself identically after a strict 28-year cycle. Therefore, 1988 + 28 = 2016.
2259
If August 15, 2011, was a Monday, what day was August 15, 2012?
Answer:
Wednesday
The year 2012 is a leap year, and the period between August 15, 2011, and August 15, 2012, includes the leap day (February 29, 2012). This full year interval contains 366 days, providing exactly 2 odd days. Monday + 2 days = Wednesday.
2260
If March 5 is a Sunday, what day of the week will April 5 be?
Answer:
Wednesday
March has 31 days. The difference between March 5 and April 5 is exactly 31 days. 31 divided by 7 leaves a remainder of 3 odd days. Moving 3 days forward from Sunday lands perfectly on Wednesday.
