Easter holiday algorithm:

Easter is a traditional festival in the west. In 325 AD, the Nicaean religious conference stipulated that the first Sunday after the full moon at the vernal equinox was Easter. Its date is not fixed, usually you have to look at the calendar to know.

Here is a simple algorithm for your reference:

The year is limited to 1900 to 2099.

NO. 1 Set the required year as y year. If you subtract 1900 from y, the difference is n;

NO.2 divide n by 19, and record the remainder as a;

No.3 divides n by 4, regardless of the remainder, and records the quotient as q;

NO.4 Divide 7A+ 1 by 19, and record the quotient as b, regardless of the remainder;

No.5 is divided by 1 1A+4-B by 29, and the remainder is recorded as m;

NO.6 divide N+Q+3 1-M by 7, and record the remainder as w;

Number 7 is 25 meters wide.

You can determine the date of Easter by getting the answer. If it is a positive number, the month is April; If it is negative, the month is March; If it is 0, it is March 3 1.
