Keep global time comparisons clear, even when calendar dates differ. Choose up to 12 cities or IANA time zones and see their local time, full date, weekday, UTC offset, and a day or night indicator. Keep places in your preferred order, rename their display labels, set a reference place, or remove them. Convert a current or manually selected source moment into the corresponding date and time in multiple target places. Copy results, save a conversion to your recent history, and revisit saved results. Save source and target groups for reuse. Compare a start and end time across your saved places, including overnight ranges. Mark an ideal time window manually; the app does not decide whether a time works for everyone. Daylight-saving transitions are handled explicitly. A nonexistent local time is identified, and repeated local times prompt you to choose the intended occurrence. Time-zone rules are bundled for offline use. Included data may not reflect future government policy changes. Places, preferences, combinations, and conversion history are stored locally on this device. The app does not request location access, require an account, or use a network time service. Choose a 12- or 24-hour clock, date format, week start, theme, and text size to suit your preferences.
