How many odd days are there in a span of 10 years, assuming the first year is a leap year?
Answer:
6
A span of 10 years starting with a leap year contains 3 leap years (e.g., Year 1, Year 5, Year 9) and 7 ordinary years. Total odd days = (3 × 2) + (7 × 1) = 6 + 7 = 13. Dividing 13 by 7 leaves exactly 6 odd days. Wait, if it's 10 years: e.g. 2000(LY), 01, 02, 03, 04(LY), 05, 06, 07, 08(LY), 09. Total 10 years. 3 LY + 7 NY = 6 + 7 = 13 days -> 6 odd days. Option C is 5, Option D is 6. I'll correct the option to D.

If today is Friday, what day of the week will it be after 365 days?
Answer:
Saturday
365 days is exactly 52 weeks and 1 odd day. Since the remainder is 1, the day shifts forward by a single day. Friday + 1 day = Saturday.
2293
Which of the following months always start on the same day of the week in any leap year?
Answer:
January and July
In a leap year, the cumulative odd days from January 1 to July 1 equals exactly 0 mod 7 (Jan: 3, Feb: 1, Mar: 3, Apr: 2, May: 3, Jun: 2 -> Total = 14). Thus, January and July start on the same day.
2294
Find the day of the week on 25th December 1995.
Answer:
Monday
1900 has 1 odd day. Next 94 years = 23 LY + 71 NY = 46 + 71 = 117 days = 5 odd days. Total to 1994 = 6 odd days. Days in 1995 to Dec 25: Jan(3) + Feb(0) + Mar(3) + Apr(2) + May(3) + Jun(2) + Jul(3) + Aug(3) + Sep(2) + Oct(3) + Nov(2) + Dec(25=4) = 30 = 2 odd days. Total odd days = 6 + 2 = 8 = 1. Day 1 is Monday.
2295
If 12th March 2005 was a Saturday, what day was 12th March 2004?
Answer:
Thursday
2004 was a leap year, meaning it contained an extra day (Feb 29). Moving backward from March 2005 to March 2004 crosses this leap day. Therefore, we subtract 2 odd days instead of 1. Saturday - 2 days = Thursday.
2296
Which of these years will have the same calendar as the year 1995?
Answer:
2006
1995 is a year of the format (Leap Year + 3) since 1992 was a leap year. Calendars for LY+3 naturally repeat after 11 years. Therefore, 1995 + 11 = 2006.
2297
If an ordinary year starts on a Monday, how many Mondays will there be in the year?
Answer:
53
An ordinary year contains exactly 365 days, which breaks down into 52 complete weeks and 1 additional day. This 1 extra day causes the starting day of the year to appear 53 times, while all other days appear 52 times.
2298
What is the interval between the years 1896 and 1904?
Answer:
8 years
1896 was a leap year. The next year divisible by 4 is 1900. However, 1900 is a century year not divisible by 400, making it an ordinary year. The next leap year after 1896 is 1904, resulting in a rare 8-year interval.
2299
If the 4th of a month is a Friday, what will be the day on the 25th of the same month?
Answer:
Friday
The difference between the two dates is 25 - 4 = 21 days. Since 21 is a perfect multiple of 7 (21 = 3 × 7), there are absolutely 0 odd days. The day of the week will remain identical, which is Friday.
2300
How many times does the 29th day of a month occur in 400 consecutive years?
Answer:
4497
Every month except February always has a 29th day. That's 11 months × 400 years = 4400 times. February has a 29th day only in leap years. In 400 years, there are 97 leap years (400/4 - 3 century non-leap years). Total = 4400 + 97 = 4497 times.
