What will be the day of the week on 02 February 3015?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. Thursday
3015 = 3000 + 14 years + 1(year 3015)
In 3000 years, 2800 years = 0 odd days
And 200 years = 10 odd days; 10/7 = 3 odd days
In 14 years (from 3001 to 3014); 14/4 = 3 leap years and 11 normal years.
In 3 leap year, odd days 6, and 11 normal years = 11 odd days
So, total odd days = 6 + 11 = 17 odd days i.e. 17/7 = 3 odd day
• In 3015, the number of days up to 02 February = 31 (Jan) + 02 (Feb) = 33/7 = 5 odd days.
• Total odd days in 3015 years up to 02 February = 3 + 3 + 5 = 11 odd days; 11/7 = 4 odd days
And 4 means Thursday.
Hence, the correct answer is Thursday.
