Adding values to date

Values can be added by calling .add function with type and amount parameters. Type is string day, month or year.

date = dateHelper(new Date());
date.add("day", 1);
date.add("month", 1);
date.add("year", 1);

Subtracting values to date

Values can be subtracted by calling .sub function with type and amount parameters. Type is string day, month or year.

date = dateHelper(new Date());
date.sub("day", 1);
date.sub("month", 1);
date.sub("year", 1);

Is date before other date

isBefore function can be used to check if date is before other.

var date = new Date(2016, 4, 3);
dateHelper(date).isBefore(new Date(2016, 4, 4)); // true

Is date after other date

isAfter function can be used to check if date is after other.

var date = new Date(2016, 4, 3);
dateHelper(date).isAfter(new Date(2016, 4, 2)); // true

Is date same as other date

isSameAs function can be used to check if date at same time as other.

var date = new Date(2016, 4, 3);
dateHelper(date).isSameAs(new Date(2016, 4, 3)); // true
