@Jamie: You don't need two Date objects. var d = new Date(); d.setMinutes(d.getMinutes() + 30);

@Grant: I assumed d2 = "I'd like to get a Date object" and d1 = "to another Date object"

@CKeene, setMinutes & getMinutes are part of plain old Javascript (though datejs does provide a whole bunch of other stuff).

FYI- this can break across Daylight Saving Time boundaries. JSFiddle demos: "spring forward" / "fall back" (Thanks @Spig for this)

@trevorgrayson If a parameter you specify is outside of the expected range, setMinutes() attempts to update the date information accordingly. For example, if you use 100, the hours will be incremented by 1 and 40 will be used for minutes.
