Frequently Asked Questions
What is a time zone?
A time zone is a region that observes the same standard time. The world is divided into 24 time zones, each one hour apart, based on the Earth's rotation. Time zones are measured as offsets from UTC (Coordinated Universal Time), which is the reference point.
What is UTC?
UTC (Coordinated Universal Time) is the primary standard for time. It is not affected by daylight saving time. UTC is also known as GMT (Greenwich Mean Time). Most time zones are expressed as offsets from UTC (e.g., EST is UTC-5).
How do I calculate time zone differences?
To convert time between zones, find the offset of both time zones from UTC. Subtract the original zone's offset from the destination zone's offset. Add this difference to the original time. If the result is negative or exceeds 24 hours, adjust by one day.
