Important Note for Teachers
about Sunrise/Sunset Data
for Monday, March 11, 2013

1. For the rest of the season, we will give you sunrise/sunset times in two formats, Local Time and Universal Time. Why this change? You will be using Universal Time for this week's Longitude Clues and other clues, so it's a good time to become familiar with it.

    • Local Time is the time people see on their clocks and follow during their daily lives in each of the world's 24 time zones. Local time matches the sun's day/night cycle in every time zone.
    • Universal Time is the same time everywhere on Earth, in all of the world's time zones. Universal Time gives us a world clock with one world time zone. Universal Time matches standard local time in Greenwich, England (UT does not adjust for daylight saving time.)
