简介

Savvy Time is a world clock, time zone converter and meeting planner in your browser toolbar. Add the cities you work with and see their local times side by side. Change the time in one place and every other place follows.

• World clock: the current time in each of your places, with its time zone, UTC offset and time difference, correct for daylight saving time on any date.
• Time zone converter: choose a date and set the time by typing it, picking it from a list or dragging the day slider, and see it in every place at once. Convert between EST, PST, GMT, UTC, CET, IST and other time zones.
• Meeting planner: Best time finds shared working hours or a fair compromise with every time slider style, even when the slider is off. Click it to compare that time. Hide the line with ×; bring it back in More → Best time.
• Search 24,000+ cities and towns, countries, regions and time zone names or abbreviations.
• Choose what each place shows: state and country, time zone, UTC offset, time difference and date.
• Color the day slider by working hours or daylight, use one color, or turn it off. Switch between 12-hour and 24-hour time, and light and dark themes that can follow your system.
• Rename, drag to reorder and sort your places, or right-click one for quick actions. Removed one by mistake? Undo brings it back.
• Your places stay saved for next time.
• Share a time: Copy times puts every place’s time and a savvytime.com link on your clipboard, ready for a chat or email. You can also open the comparison on savvytime.com, or add the time to Google Calendar, Outlook.com or any calendar app with an .ics file.
• Convert selected times: select a time on a page, right-click and choose Convert “…” with Savvy Time. See how it was read and use Change to correct it. Supports time ranges, time zones and calendar invitation times. Selected text stays on your device; no page scanning is needed.
• Optional toolbar clock: choose a saved place in More → Toolbar clock to see its time without opening the converter. Uses your 12- or 24-hour setting and starts off.
• Keep the converter beside your work with More → Open in sidebar. Places, settings and selected time stay in step with the popup.

Works offline: time zone and daylight saving rules are built in and kept up to date through extension updates. Opening savvytime.com or an online calendar needs an internet connection.

Useful for remote teams, family abroad, travel planning and international events.
