Tests:

luxon
var date1 = luxon.DateTime.fromJSDate(__date__); var date2 = luxon.DateTime.fromJSDate(__another_date__); date1.diff(date2, "minute"); date1.diff(date2, "hour"); date1.diff(date2, "day"); date1.diff(date2, "week");
dayjs
var date1 = dayjs(__date__); var date2 = dayjs(__another_date__); date1.diff(date2, "minute"); date1.diff(date2, "hour"); date1.diff(date2, "day"); date1.diff(date2, "week");
vanilla
var date1 = __date__; var date2 = __another_date__; diffDate(date1, date2, "minute"); diffDate(date1, date2, "hour"); diffDate(date1, date2, "day"); diffDate(date1, date2, "week");
