No. of odd days | Ordinary year | Leap year |
365 ÷ 7 = 52 weeks + 1 odd day | 366 ÷ 7 = 52 weeks + 2 odd day |
And,
Years | No. of odd days |
100 | 5 |
200 | 3 |
300 | 1 |
400 | 0 |
Note : Multiple of 400 years i.e 800, 1200, 1600, 2000 will also have 0 odds days.
Days | No. of odd days |
Sunday | 0 |
Monday | 1 |
Tuesday | 2 |
Wednesday | 3 |
Thursday | 4 |
Friday | 5 |
Saturday | 6 |
Now, calculating total number of odd days:
Total odd days till 6 January 2010 = 4 + 0 + 6 ⇒ 10 ÷ 7 = 3
Thus, "3" is the code for 'Wednesday'.
Hence, "Wednesday" is the correct answer.
