Time Zone Converter
Compare times across multiple time zones and cities with automatic Daylight Saving Time adjustments.
The selected city follows Daylight Saving Time.
Due to a clock change, this local time does not exist and has been automatically adjusted.
- Eastern Time (ET) automatically observes EST (Standard) from Nov-Mar and EDT (Daylight) from Mar-Nov.
The converter handles this switch for you based on the date selected.

Understanding Time Zones & Daylight Saving Time
Why Time Zones Exist
To facilitate global coordination while respecting the natural cycle of day and night, the world is divided into longitudinal stripes called time zones. The reference point for all time zones is the Prime Meridian in Greenwich, London (GMT/UTC). As you move east, time is ahead (+); as you move west, time is behind (-).
The Complexity of Daylight Saving Time (DST)
Daylight Saving Time is the practice of advancing clocks during warmer months so that darkness falls later each day according to the clock. While intended to save energy, it creates significant confusion for global scheduling.
- North America & Europe: Typically shift clocks in March and late October/November.
- Southern Hemisphere: Shifts occur in opposite months (starting around September/October).
- No DST: Most countries near the equator (e.g., India, Singapore, parts of Africa) do not observe DST at all.
Did you know? A meeting scheduled between New York (EST) and London (GMT) has a 5-hour gap in winter, but only a 4-hour gap for a brief window in March when the US starts DST before the UK. UtilBelt automatically accounts for these shifts.
