Frequently Asked Questions
What is a time zone and how does UTC work?
A time zone is a region that observes a uniform standard time. UTC (Coordinated Universal Time) is the primary time standard. All other time zones are expressed as offsets from UTC — for example, IST is UTC+5:30 and EST is UTC-5.
Does this tool handle Daylight Saving Time (DST)?
Yes. DST is handled automatically using your browser's built-in Intl API, which follows the IANA time zone database. The tool always uses the correct offset for the selected date, accounting for DST transitions.
What does "Next Day" or "Previous Day" mean?
When converting across large time differences, the converted time may land on a different calendar date. "Next Day" means it is already tomorrow in the target zone, and "Previous Day" means it is still yesterday.
Can I share a specific time conversion with others?
Yes! Click the "Share Link" button to generate a URL that encodes the selected zones and time. Anyone who opens the link will see the same conversion pre-loaded.
Is my data sent to any server?
No. All time zone conversions happen entirely in your browser using the JavaScript Intl API. No data is sent to Usely.in or any third party.
