Build your Timezone Meeting Picker with AI in under 5 minutes

Build a World-Time-Buddy-style meeting time picker with a 24-cell hour strip per participant, color-coded by working / early / evening / asleep tier, plus an automatic 'best meeting times' panel that surfaces UTC bands where everyone is awake — generated from a single prompt.

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.

Frequently asked questions

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.).
