Zovo Meeting Planner

A time zone converter and meeting planner that gets daylight saving time right.

Convert time zones with a date: ask for 3pm PST on November 3 in Warsaw and Sydney, EST to IST, or New York to London, and Zovo Meeting Planner returns the same moment in every place with its UTC offset, abbreviation, a +1 day marker when the date changes, and the hour difference. It uses the full IANA time zone database, so it handles the weeks in March and October/November when the US and Europe change clocks on different dates (New York and London are 4 hours apart, not 5), half-hour and 45-minute zones such as India and Nepal, and Lord Howe Island's 30-minute daylight saving shift. When a clock change happens within 7 days, it says so. Times that do not exist (clocks spring forward) are explained and moved; times that happen twice (clocks fall back) show both.

Time zone converter for meetings: give 2 to 8 places, a date or a range of up to 14 days, and a meeting length. The meeting planner ranks distinct slots by how many people are inside working hours and how early or late it is for the person worst off (night hours and days off count extra), and shows a 24-hour timeline per place with working hours shaded. When a time works for everyone, it shows the whole window of start times that keep everyone inside working hours and the other days with the same local times. When no time in your dates works for everyone, it finds the closest one in the following week. Set working hours per person, or work weeks such as Sunday-Thursday. Tap any hour to check another start time, and download a calendar (.ics) file for the slot you pick.

Places can be any of about 500 cities, a city with its state or country (Portland, Maine), US states, countries, IANA zone names (Europe/Berlin), UTC offsets (UTC+5:30), or abbreviations like PST, CET, IST, AEST. Ambiguous abbreviations are flagged.

Limitations: it does not read or write your calendar, check availability, or send invitations, and public holidays are not considered.
