May 12 1984 was on a Saturday. For any date in the 1900s, you can figure out the day of the week in 4 steps: • Month #: (in order, the month #s are: 1 4 4 0 2 5 0 3 6 1 4 6) May => 2 • Date #: 12÷7=1 with a remainder of 5 12th => 5 • Year #: 84÷7=12 with a remainder of 0 '84 => 0 • Leap Year #: 84÷4=21, 21÷7=3 with a remainder of 0 '84 => 0 Finally, divide the sum of all (4) numbers by 7: the remainder is the day o the week 7 ÷ 7 = 1, with a remainder of 0, or the day before the first day of the week Sun = 1st day of the week, so this day (5.12.84) was Saturday.
It was a Sunday.
