Date Format Compatiblity Cross Browser

Solution 1

Using a format date from momment js (plugin)

moment().format('MMMM Do YYYY, h:mm:ss a'); // January 7th 2019, 2:48:53 pm
moment().format('dddd');                    // Monday
moment().format("MMM Do YY");               // Jan 7th 19
moment().format('YYYY [escaped] YYYY');     // 2019 escaped 2019
moment().format();                          // 2019-01-07T14:48:53+08:00

The Solution

The problem lies in the format that you pass the required date to the Date() object. For some reason, and don’t ask me why, the two aforementioned browsers surprisingly do not support the date format “yyyy-mm-dd” and therefore fail.
