Just a reminder, in case you forget, or perhaps did not know, tonight, if you live in North America, you advance your clock: + 1 hour
So...you lose one hour sleep. Here, we change the clock at 3:00 A.M., but of course, change it maybe before you go to bed, or when you wake up tomorrow morning.
Daylight Savings begins tonight/tomorrow, after 3:00 a.m. EST (Eastern Standard Time).
