What was the day of the week on 15 August 2013?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Thursday.
15 August 2013 will have 2012 complete years and days up to 15 August.
2013 = 2000 + 12 years + days upto 15 August
Since 2013 is a non-leap year:
Days upto 15 August = 31 + 28 + 31 + 30 + 31 + 30 + 31 + 15 = 227 days
Now we need to calculate the number of odd days:
2000 years will have 0 odd days.
There are 3 leap years and 9 non-leap years from 2001 to 2012.
Therefore, no. of odd days in this period = 1 odd day
227 days will have 3 odd days.
So, total odd days = 0 + 1 + 3 = 4
Hence, it will be Thursday on 15 August 2013.
