Frequently Asked Questions
How does world time conversion work?
Select your base city and time, then choose a target city or time zone to see the converted local time. The converter accounts for daylight saving time automatically.
What is a time zone offset?
A time zone offset is the difference in hours between a specific time zone and UTC (Coordinated Universal Time). For example, New York is UTC-5, London is UTC+0, and Tokyo is UTC+9.
Does daylight saving time affect conversions?
Yes. During daylight saving time (DST), clocks shift forward by one hour in many regions. This calculator updates DST changes automatically, but not all countries observe DST.
How many time zones are there?
There are 24 primary time zones, each roughly 15 degrees of longitude apart. Some regions use 30 or 45-minute offsets, resulting in over 40 distinct time zones worldwide.
What is UTC?
UTC (Coordinated Universal Time) is the primary time standard from which all other time zones are offset. It does not observe daylight saving time, making it a stable reference for international scheduling.
