Eastern (US) Standard Time

For those of you who forgot, today begins EST. That means that if you have not set your clocks back one hour, you should do today.
Otherwise, you may be an hour late for everything today.
Daylight saving time ends at 2 am today. As the saying goes when it comes to remembering how to reset your clock, "fall back, spring forward."
EST is used to run from the last Sunday in October to first Sunday in April. But that changed in 2007 when the federal government changed the first Sunday of November to the first Sunday in March.
This calendar shortens the standard four to five weeks.
