Where is the start of anew day measured?

Answer 1

The start of a new day is typically measured at midnight, which is defined as 12:00 AM in the 24-hour clock system. This marks the transition from one day to the next. In terms of time zones, the beginning of a new day varies across different regions, as it is determined by local time based on the Earth's rotation relative to the sun. The International Date Line serves as a key reference point for when a new day officially begins in different parts of the world.
