Time Zones and Maps

Today we talked about maps and how we have time zones. On maps there is a grid, which are made up of longitude (0 degrees to 180 degrees East to East) lines and latitude (0 degrees to 90 degrees North to South) lines. The intersection of longitude and latitude lines show specific points on the Earth For more accuracy you would divide each degree by 60 mins and then each minute by 60 seconds. For time zones since the Earth is 360 degrees, you divide 360 by 24 hours in a day and get 15 degrees. Every 15 degrees on a map is one hour back or one hour forward. We also talked about how weird it is that we start our day at 12am instead of 0am. It is also weird that we go from 12 to 1. We don't count like 12, 1, 2, 3, 4.... so why would the time be made like that? I think we should use military time because it starts at 0:00am and goes all the way to 23:59pm.
