Hi kannana. For every 400 years you get 0 odd days. Keep remember. 2000=400+400+400+400+400.
=0+0+0+0+0.
=0.
=0+0+0+0+0.
=0.

@Gautam
Formula/Shortcut: Odd days in 1600 years = 0
Formula/Shortcut: Odd days in 400 years = 0
Therefore, 1600 + 400 = 2000.
2000 + { Jan (31). Feb(28). March(31) April 1st (1) }
(31 + 28 + 31 + 1) = 91 days 0 odd days.
Therefore On 1st April, 2001 it was Sunday.
From this data, we can find that
In April, 2001 Wednesday falls on 4th, 11th, 18th and 25th.
Hope this will help you. Have a nice day!

See Mr. Ravi, 2000=1600+400 (why because those are leap century years)
how is possible 91 is odd day.
See, 91/7 = 13weeks + 0 days.
I already said that extra days of a week are odd days. Here we have 0 days (so, we don't have odd days).

Odd days are after completion of a week/weeks any extra days we get are called odd days.
For example:
Take a year, one year contains 365 days (non leap year), divide it with 7
= 365/7
= 52+1 (meaning that 52 weeks + 1 odd days).
