World Time Board - Time Zones

If you work across countries, or your family and friends live abroad, you end up doing the same sum over and over: "what time is it there right now?" World Time Board removes that step. Add your cities once and their current times sit side by side on one screen — and a single slider shows a meeting time in everyone's local clock. ■ Time Board — the current time at a glance · Every city you added, all on one screen · A 24-cell bar per city colouring work hours, early morning, evening and night · Zone abbreviation (KST, EST …), a DST badge and an upcoming-transition notice · Sunrise and sunset times, 12- or 24-hour clock, optional seconds · Drag to reorder, or sort by offset, name or continent · City nicknames, notes, groups and per-city working hours ■ Meeting planner — find a time that works for everyone · Pick a date, drag the slider, and read every city's local time and how well it fits · Best-time finder scans all 48 slots of the day and picks the one that suits everyone · City × 24-hour overlap heat map — tap a column to jump to that hour · Working hours, weekends and public holidays are taken into account · Copy as text, share as an image card, or export to your calendar (.ics) ■ Convert — any time, any city · Take any moment in any city and read it in all the others ■ Map — see where it is day and night right now · A live day/night terminator on a world map, with pins for your cities ■ City alarms · Alarms that ring at the other city's local time and follow its DST changes ■ Fully offline Every calculation uses only your device clock and the operating system's IANA time zone data. No server, no sign-in, no account. It works in flight mode. Your city list and settings stay on the device and are never uploaded. ■ About ads The core is always free: reading the time, adding and removing cities, and the meeting slider are never behind an ad. Rewarded ads only open extras — 24-hour banner removal, extra city and group slots, extra best-time and calendar uses, clock skins, watermark removal, full time-zone search and holiday data — and those extras still unlock when no ad is available or you are offline. ■ Languages English · 한국어 · 日本語 · 中文 · Español · Français · Deutsch · Português · Bahasa Indonesia · Tiếng Việt Starts with a catalogue of 102 cities and can search every IANA time zone. Holiday data is an offline reference set — always confirm against an official calendar. Contact: [email protected]
