Minimum2.7.0+

moment.min(Moment[,Moment...]);
moment.min(Moment[]);

Returns the minimum (most distant past) of the given moment instances.

For example:

var a = moment().subtract(1, 'day');
var b = moment().add(1, 'day');
moment.min(a, b);  // a
moment.min([a, b]); // a

With no arguments the function returns a moment instance with the current time.

From version 2.10.5, if an invalid moment is one of the arguments, the resultis an invalid moment.

moment.min(moment(), moment.invalid()).isValid() === false
moment.min(moment.invalid(), moment()).isValid() === false
moment.min([moment(), moment.invalid()]).isValid() === false
moment.min([moment.invalid(), moment()]).isValid() === false
