Learn how time zones actually work
Short, fact-checked explanations — no filler.
- What Is UTC?UTC (Coordinated Universal Time) is the reference point every time zone is measured against. Here is what it actually is — and is not.
- GMT vs UTC: What’s the Difference?GMT and UTC are used almost interchangeably, but they are not defined the same way. Here is the practical difference.
- How Daylight Saving Time WorksDaylight saving time moves clocks forward in spring and back in autumn — but not everywhere. Here is who observes it and why it matters for scheduling.
- EST vs EDT: What’s the Difference?EST and EDT are not two different time zones — they’re the same zone at two different times of year. Here is exactly how it works.
