London When time is it somewhere else? If it is 7AM in Lake Charles, what time is it in London? How do I find out? Memorized some chart? Call and wake them up? Google it?

Fact #8

When is “today” not “today”?

An imaginary line on the Earth's surface, 180° from Greenwich. As the Earth rotates, each day first begins and ends on the line. A traveler going east over the line sets their calendar back one day, and going west adds on day.

When is it right now? Lets look at some places and tell when it is right now.

Fact #11

Universal TimeThe world is divided up into about 24 time

zones. Standard time within most time zones is an integral number of hours offset from a time scale called Coordinated Universal Time (abbreviated UTC), maintained by a large number of very precise “atomic clocks” at laboratories around the world, including the U.S. Naval Observatory.
