  • It's AumSum Time

  • Why do we have different time zones?

  • Coz we have different watches.

  • No.

  • Our earth rotates on its own axis.

  • Due to this rotation, different parts of the earth receive different amounts of sunlight.

  • Thus causing morning, noon, evening and night.

  • Now, if we had one time zone, then 12 pm would be noon at some places.

  • But it would be night or evening at other places which would be inconvenient.

  • Hence, scientists made different time zones according to the earth's rotation with respect to the sun.

  • But how?

  • The earth makes one full 360 degrees rotation in 24 hours.

  • This means in one hour, the earth moves by 15 degrees.

  • Using this information, scientist divided the planet into 24 sections or time zones.

  • Each section or region was about 15 degrees wide and had a specific standard time.

  • This helped us know the proper time of the day in that part of the earth.

  • Hold on guys.
