The following example compares today's date with January 14, 2100:
var today, someday, text; today = new Date();/* w ww . j av a 2s . co m*/ someday = new Date(); someday.setFullYear(2100, 0, 14); if (someday > today) { text = "Today is before January 14, 2100."; } else { text = "Today is after January 14, 2100."; } console.log(text);
JavaScript counts months from 0 to 11. January is 0. December is 11.
