V8 doesn't support Georgian localization this package adds this support to Intl.DateTimeFormat and Date.toLocaleString.
Add
import 'intl-ka';
somewhere at the beginning of you application e.g. index.{js|ts}
var date = new Intl.DateTimeFormat('ka', {
milisecond: 'short', era: 'long', month: 'short',
day: '2-digit', year: 'numeric', minute: 'numeric',
second: 'numeric', weekday: 'short', hour12: false, hour: '2-digit'
});
date.format(new Date(Date.UTC(2020, 11, 20, 3, 23, 16, 738)));
