What is a timezone meeting picker?

A timezone meeting picker answers 'when can our team in NYC, London, and Singapore actually meet?' without the manual addition that always produces an off-by-one mistake. World Time Buddy is the long-standing favourite; Every Time Zone serves the simpler case; Calendly handles the scheduling but expects participants to pick from offered slots. The shape is simple: name the participants and their timezones, render an hour strip per person side-by-side, shade the working hours, and surface the windows where everyone is awake and ideally in business hours. The complication is DST — different countries change clocks on different dates, so a meeting that worked last week breaks next week unless the picker handles transitions correctly.

Common features

  • Per-participant 24-cell hour strip aligned by UTC
  • Working-hours band shaded per participant's local time
  • Best-time suggestion that maximises overlap inside working hours
  • Quick add via city name autocomplete
  • DST-aware time math so future dates render correctly
  • Shareable URL — drop in Slack, everyone sees the same view
  • Per-meeting save with title and notes
  • Recurring-meeting view (weekly standup time across DST)
  • Calendar integration — pick a slot, create calendar event
  • Mobile-friendly responsive layout

Real-world examples

Distributed team standup

Weekly standup time visualised across 5 timezones. DST-aware so the meeting time stays sane through spring and autumn transitions.

One-off cross-region kickoff

Kickoff meeting with 12 attendees across 4 timezones. Shareable URL drops in the email, no signups required.

Personal multi-timezone tracker

For someone with family or work spread across timezones. Quick reference for 'is it OK to message them now?'

Why FloopFloop fits timezone meeting picker projects

World Time Buddy works but is ad-supported and the URL doesn't read as part of your brand when shared. Calendly is great for one-on-one scheduling and overkill for the 'find the overlap' problem. FloopFloop ships you a meeting picker that lives on your own subdomain, integrates with your calendar of choice, and supports the specific participants and recurring meetings your team runs. The DST math is solved math; the shareable URL is your own brand.

Build a World-Time-Buddy-style meeting picker. Each participant has a name, an IANA time zone, and configurable working hours (default 9–18 local). Render a 24-cell horizontal strip per participant where each cell shows their local hour for the corresponding UTC hour, color-coded by tier (work / early / evening / asleep). Add a 'best meeting times' panel that surfaces UTC bands where everyone is in work hours, with per-participant local equivalents.

Create a remote-team timezone dashboard. List every team member with their flag, name, current local time, and a live 'in / out / sleeping' status badge based on their working hours. Pin team members to a sidebar with one-click 'show in main strip' so the operator can compare an ad-hoc subset (e.g. the 4 people on the launch standup) without re-typing everyone every time.

Design an Every-Time-Zone clone for a single-tenant intranet. Time strip across the top showing UTC reference, rows for each member showing their day-night shading, a draggable 'meeting marker' that snaps to 15-minute intervals and shows the local time for every member as you drag, and a 'send invite' button that opens the mail client with the time pre-filled.

Build a stand-up rotation tool for a follow-the-sun team. List members in time-zone order (earliest local hour first), highlight whose working-hours window is starting next, generate a 'who's online right now' summary, and a /weekly button that picks one standup time per weekday that rotates fairly across time zones over the month.

Häufig gestellte Fragen

How does this compare to World Time Buddy / Every Time Zone / Calendly's timezone picker?
World Time Buddy and Every Time Zone are great web tools for ad-hoc time conversion — they don't persist participants across sessions or surface 'best times' programmatically. Calendly's timezone picker is for 1-on-1 appointments, not group-of-N meetings. This template is the group-of-N case: persist participants, compute the overlap automatically, render the answer in one screen. It also runs entirely client-side in your own browser; nothing leaks to a third-party service.
How does the 'best meeting times' algorithm work?
For every UTC hour 0–23, the template checks if EVERY participant is in their 'work' tier (between their configured workStart and workEnd). Consecutive 'yes' hours coalesce into bands. The panel shows the UTC range and the per-participant local equivalent so you can sanity-check at a glance. Evening / early hours intentionally don't count toward 'best' so the tool doesn't recommend a 9pm meeting unless you genuinely have no other choice (the SF↔Singapore problem) — in which case the panel surfaces a 'no overlap' state with an actionable suggestion to widen someone's working hours or accept the from-home call.
Does it handle daylight savings transitions?
Yes — all timezone math goes through native Intl.DateTimeFormat, which uses the IANA tzdata rules in effect at the rendered instant. So a meeting picker rendered on March 1 sees Amsterdam as UTC+1 (CET); rendered on April 1 it sees Amsterdam as UTC+2 (CEST). No moment/dayjs/luxon dependency to fall out of date.
Where are participants stored?
The default template uses browser localStorage so the picker works instantly with no signup. Refine with 'add a Postgres backend so my team's participant list syncs across browsers' to move to server storage — the codegen scaffolds the schema, the API routes, and the sync logic in one round. The scanner blocks every external database (Supabase / Firebase / MongoDB) so the data stays on your own per-tenant Postgres schema.
Can I share a meeting time as a link?
Not in the default template. For sharing refine with 'add a /share/[meetingId] route that renders a read-only view of the picker with a specific UTC hour highlighted' — the codegen wires the route, the deep-link parser, and the highlight state. Pair it with 'add a Copy as iCal button' to generate a downloadable .ics file the recipient can drop into Outlook / Google Calendar / Apple Calendar.
How many participants can it handle?
The strip render is O(N participants × 24 cells) = ~24 DOM nodes per row. Comfortably handles 50 participants on a laptop; past that the page scrolls but stays interactive. For 500+ participants (a global all-hands list) refine with 'add a virtualized list using react-window so only visible rows render' — the codegen wires the virtualizer and the row-renderer adapter in one round.
What timezones are supported?
The full IANA database — ~430 zones via Intl.supportedValuesOf('timeZone'). The picker filters out legacy Etc/* and SystemV/* (relics of the old POSIX scheme) so the list is the modern continent/city set everyone recognises (Europe/Amsterdam, America/Los_Angeles, Asia/Singapore, etc.).
