20 19 What day is New Year's Day?

The first method is simple and rude, looking up the calendar.

Second, calculate the number of days from 20 190 10 1 to 20 19060 1.

3 1+28+30+3 1+3 1= 15 1 15 1/7=2 1…4

Thursday and Saturday in four days.

Third, it has nothing to do with New Year's Day, 20 19060 1.

The date code is: date 1.

The month code is: June corresponds to 3 (the last explanation here)

The year code is: the last two digits 19/4=4…3, regardless of the remainder, 4+ 19=23, 23/7=3…2, where the year code is the remainder 2.

Add up to 1+3+2=6, so 20 19 Children's Day is Saturday.

Explain the month code: May is 0, August is 1, February, March, November is 2, June is 3, September and December is 4, April and July is 5, January and October is 6, leap year is changed to 1, and January is changed to 5.
