What was the day of the work on 16^th June 1998 ?

Tuesday

16th june 1998

( 1997 years + 1-1-1998 to 16-6-1998 )

Number of Odd days in 1600 years = 0

Number of Odd days in 300 years = 5 ×  3 = 15 = 1

In 97 years = 24 leap  years + 73 ordinary years

Number of odd days in 97 years = 2 × 24 + 73 = 121 = 2 odd days

Number of odd days from 1-1-1998 to 16-6-1998

= ( 31 + 28 + 31 + 30 + 31 + 16 )

= 167 odd days

= 6 odd days

Total number of odd days = 0 + 1 + 2 + 6 = 2 odd days 

So, It is Tuesday on 16th june 1998
