Interesting Facts About Time Zones You May Not Know

Before the 19th century, every town set clocks by the sun. Railroads forced standardization—leading to the 1884 International Meridian Conference that created 24 global zones anchored by GMT.
DST shifts clocks forward in spring to extend evening daylight. Over 70 countries use it, but tropical nations (e.g., India, Japan) and Arizona (USA) opt out due to minimal daylight variation.
Use UTC for scheduling, rotate meeting times fairly, label deadlines with time zones, and respect core working hours. Async communication reduces burnout across time zones.
We use the IANA Time Zone Database—the global standard used by Apple, Google, and Linux—which accounts for current offsets, DST rules, and historical changes.
Many sites use static UTC offsets that ignore DST or political changes. We map cities to official IANA identifiers (e.g., “America/Chicago”) for millisecond accuracy.
GMT is a time zone based on solar time at Greenwich. UTC is a scientific time standard based on atomic clocks. For civil purposes, they’re often used interchangeably—but UTC is more precise.
Yes—via the IANA database—but leap seconds rarely affect everyday timekeeping. Our system handles them transparently without user intervention.
Our mission is to eliminate time zone confusion in an interconnected world. Whether you’re scheduling a Zoom call, tracking shipments, or planning travel, precise time conversion is essential.
We rely on the IANA Time Zone Database—the same system used by major tech companies—and update it weekly to reflect legislative changes (e.g., Morocco’s Ramadan DST suspension).
Unlike ad-heavy alternatives, we prioritize accuracy and user experience: no pop-ups, no fake urgency, and no data selling. Built by a small team passionate about solving “small” problems that cause big headaches.
