If Feb 12th, 1986 falls on Wednesday then Jan 1st, 1987 falls on which day?

To solve this problem, we need to calculate the number of days between February 12, 1986, and January 1, 1987, and then determine what day of the week it would be.

1. Calculate the number of days in each month from February 12, 1986, to January 1, 1987:

   • February 1986: 29 - 12 = 17 days (1986 is a common year, so February has 28 days)
   • March 1986: 31 days
   • April 1986: 30 days
   • May 1986: 31 days
   • June 1986: 30 days
   • July 1986: 31 days
   • August 1986: 31 days
   • September 1986: 30 days
   • October 1986: 31 days
   • November 1986: 30 days
   • December 1986: 31 days
   • January 1987: 1 day

2. Add up all these days: 17 + 31 + 30 + 31 + 30 + 31 + 31 + 30 + 31 + 30 + 31 + 1 = 324 days

3. Divide the total number of days by 7 (since there are 7 days in a week) to find out how many complete weeks there are and what the remainder is: 324 ÷ 7 = 46 weeks and 2 days

4. Since February 12, 1986, is a Wednesday, and there are 2 days left after counting complete weeks, we just need to count two days forward from Wednesday. So, January 1, 1987, falls on a Friday.
