Is there an exact time/date every year that Daylight Savings Time occurs?
Is there a way to know ahead of time that it's coming up?

Daylight Saving Time is always the Second Sunday in March in the US. We revert back to Standard time the First Sunday in November :)

There is a specific time when it is done in the U.S, but the dates may vary annually. Normally, it starts on 2 a.m. on the Second Sunday in March and ends on the 2 a.m. on the First Sunday of November. To get more details on this, visit http://wwp.greenwichmeantime.com/time-zone/rules/usa/.
