How many degrees of longitude correspond to each hour of time change in the time zones?

Each hour of time change corresponds to a shift of 15 degrees of longitude. This is due to the Earth’s rotation, which completes a full 360 degrees in 24 hours. Therefore, when you divide 360 degrees by 24 hours, you arrive at 15 degrees of longitude for each hour. This system of dividing time into time zones is based on the mean solar time, allowing for standardized timekeeping across different regions of the world. It helps in coordinating activities across different geographic areas.
