Journey North Mystery Class: A study of sunlight and the seasons

Important Note for Teachers
about Sunrise/Sunset Data
for Monday, March 12, 2012

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.)
