What was the day of the week on 3rd April, 1838?

Question

Accepted Answer

Tuesday. Use 1 January 2000, a known Saturday, as the reference date, and work backward to 1838. From 1 January 1838 to 1 January 2000 there are 123 ordinary year(s) and 39 leap year(s). An ordinary year has 365 days = 52 weeks + 1 odd day. A leap year has 366 days = 52 weeks + 2 odd days. So the years alone contribute (123×1 + 39×2) mod 7 = 5 odd day(s). 3rd April 1838 is 92 day(s) into 1838, so the gap back to 1 January 2000 is (5 − 92) mod 7 = 4 day(s). Counting 4 day(s) backward from Saturday lands on Tuesday. Check: 3rd April 1838 is indeed a Tuesday.
