1982 1
1983 1
1984 2
1985 1
1986 1
1987 1
1988 2

From the above table, Number of odd days from 18.09.1977 to 18.09.1983 = 7,

i.e., 0 odd days

It means that in 1983, 18th September would fall on Sunday.

From the above table, a number of odd days from 18.09.1977 to 18.09.1988 = 14

i.e., 0 odd days.

As, 16th of the month is third Thursday, the day which is two weeks after this day is fifth Thursday.

So, one day after 5th Thursday is 5th Friday.
