Question

The calender for the year 1982 is the same as which year?

Answer 1

Count the number of days from 1982 onwards to get 0 odd day

1982	1983	1984	1985	1986	1987
1	1	2	1	1	1

= 7 or 0 odd days
Calender for 1982 is same as 1988 But 1982 is a non-leap year and 1988 is a leap year hence the calender for 1982 and 1988 will never be same Thus from 1988 onwards again we have to count for the total number of odd days to 7 or a multiple of seven

1988	1989	1990	1991	1992
2	1	1	1	2

= 7 days
$\therefore$ Calender for 1982 will be same as 1993
