If you are born in central time zone and you travel back to mountain time zone, do you celebrate your birthday according to central time or mountain time?
A time zone is a designated area of the Earth that observes the same standard time. It is used to synchronize clocks and keep time consistent across different regions.
There are 40 different time zones around the world, with some countries having multiple time zones within their borders.
Time zones were created to make it easier for people to coordinate and schedule activities across different regions. Before the concept of time zones, each city and town had its own local time, which could make communication and travel difficult.
Time zones are determined by lines of longitude, with each time zone being roughly 15 degrees of longitude wide. The primary reference point for time zones is the Prime Meridian, which runs through Greenwich, England.
Daylight saving time (DST) is the practice of moving clocks forward by one hour during the summer months in order to have more daylight in the evening. This is done in an effort to save energy and make better use of natural sunlight. Not all countries observe DST and it is a controversial topic in some places.
