Question

What’s the best way to compare a Java date with Javascript date for greater than or less than comparison?

Java date format: 1985-01-01T00:00:00.000-06:00

Javascript date format: Tue Jan 29 1980 00:00:00 GMT-0600

Answer 1

If you have two date objects, you can compare them directly:

var date0 = new Date(2012,0,1); // 1 Jan 2012
var date1 = new Date(2012,1,1); // 1 Feb 2012

if (date0 < date1)  { /* true */ }

Otherwise, if both dates are ISO8601 dates in the same time zone, you can compare them as strings:

var date0 = '2012-01-01T00:00:00.000';
var date1 = '2012-02-01T00:00:00.000';

if (date0 < date1)  { /* true */ }
