Frequently Asked Questions
What is UTC?
UTC (Coordinated Universal Time) is the primary time standard used to regulate clocks worldwide. It never observes daylight saving time and serves as the reference point from which all other time zones are offset.
Does this converter handle daylight saving time?
Yes. The converter relies on your browser's built-in IANA time zone database, which knows the exact DST rules for every region. Change the date to any time of year — winter or summer — and the correct offset is applied automatically.
What is the difference between EST and EDT?
EST (Eastern Standard Time) is UTC−5, observed from November to March. EDT (Eastern Daylight Time) is UTC−4, observed from March to November when clocks are moved forward by one hour. This converter shows the correct abbreviation for whatever date you select.
Why does India have a half-hour offset?
India Standard Time is UTC+5:30, a deliberate choice made at independence to split the difference across the country's width. Nepal goes even further with UTC+5:45. These fractional offsets are supported fully by this converter.
