회의 계획기

Scheduling a meeting across time zones is deceptively hard. The moment your attendees are spread across different cities — a colleague in London, a client in New York, a teammate in Singapore — a time that feels perfectly reasonable to you can land in the middle of someone else's night. This Meeting Planner takes the mental math out of it: instead of converting each person's time in your head one at a time, you see everyone's working hours side by side and pick a slot that genuinely works for the whole group.

Add each participant's city or time zone and the planner lays them out as a grid of hours, so overlapping working hours are visible at a glance rather than something you have to reason about. Drag the time slider or click an hour and every location updates at once, letting you preview exactly what a proposed meeting time means locally for each person before you send the invite. It doubles as a meeting scheduler and a meeting time planner: whether you're coordinating a standup for a distributed team, booking a call with an overseas client, or organizing an international webinar, the goal is the same — find a time that's fair to everyone, not just convenient for you.

Daylight saving time is the quiet source of most scheduling mistakes, because regions switch on different dates and some don't switch at all. The planner uses the IANA time zone database, so each city's local time reflects its current daylight saving rules automatically and the slot you pick stays correct. Everything runs in your browser with no account and nothing uploaded, which makes it fast to use repeatedly — a quick check before you propose a time, and a shareable answer for every attendee's local zone once you've settled on one.
