Description

I have an idea on the implementation of date library:

Wenyan JS equivalent
吾有一時。名之曰「今」。 var 今 = new Date();
吾有一時。曰二千八年八月八日八時八分八秒。名之曰「昔」。 var 昔 = new Date(2008, 8 - 1, 8, 8, 8, 8);
夫「今」之年。 今.getFullYear();
夫「今」之月。 今.getMonth() + 1;
夫「今」之日。 今.getDate();
夫「今」之時。 今.getHours();
夫「今」之分。 今.getMinutes();
夫「今」之秒。 今.getSeconds();
夫「今」之毫秒。 今.getMilliseconds();
夫「今」之曜。 今.getDay();
昔之「昔」之年者。今二千十八是矣。 昔.setFullYear(2018);
昔之「昔」之月者。今十二是矣。 昔.setMonth(12 - 1);

TODO add functions for date-time calculations (no JS equivalents yet)

Contributor guide

Research direction
Implement the date library by mapping Wenyan syntax to JavaScript Date methods as shown in the proposal. Add functions for date time calculations like adding days, months, etc.
