They are just two separate events (holidays, events, celebrations, whatever you want to call them) that happen to be on similar topics, but still fall on different days. (Plus, it helps the earth twice!)
24 hours and 1 day on earth
I THINK ABOUT AN HOUR. TRY THE EARTH HOUR WEBSITE.
The 24-hour day on Earth is primarily caused by the planet's rotation on its axis. As Earth rotates, different parts of the planet are exposed to sunlight, creating day and night. This rotation period has been relatively consistent over time, leading to the establishment of a 24-hour day.
24 hour day
Earth has a 24 hour day and Mars has a 25 hour day.
Earth Day April 22nd Arbor Day (varies by state) Earth Hour was on March 26th this year.
24 hour
No; Earth Day is April 22. However, the last Saturday in March (the 26 in 2011) is the observance of "Earth Hour", when businesses and individuals commit to not using electricity for one hour to demonstrate their support for the Earth, the environmental movement, and Worldwide Fund for Nature.
23 hours instead of one day (because not all of the world has a day of 24 hours)
One earth day is 24 hours no matter where you are.
dag is the word for day in Dutch. This is a 24 hour period on earth.
The next Earth Hour event will take place on March 28, 2009. Earth Hour takes place from 8:00 - 9:00 pm in their respective time zone in every city. Earth Day is celebrated each year on April 22nd.
