Meeting Time Planner

Find the best hour for a call across two timezones — every hour rated great, workable, or unsociable.

Overview

A two-timezone meeting-time finder: pick your zone and your guest's zone, and a 24-row table shows every start hour of the day with the corresponding local time in both places and a plain rating — great for both, workable, or unsociable. Click a row to select the hour you prefer.

How It Works

Choose your timezone and your guest's timezone from the dropdowns (your zone defaults to the browser's own). The table lists 24 start hours; each row displays the wall-clock time that hour produces in both zones and a colour-coded rating: green when the whole meeting, from the start hour to the last minute of the chosen duration, sits inside 09:00-17:00 in both zones, amber when start and end both fall within the wider 08:00-19:00 window, red otherwise. Set a duration between 15 and 240 minutes in 15-minute steps - it changes the ratings, because the whole slot has to fit - and click any row, or move the Your start hour slider, to mark that start hour as your pick.

Step-by-Step Usage Guide

  1. Confirm your timezone, then pick your guest's from the dropdown.
  2. Scan for green rows — both parties in business hours.
  3. Click a row to lock in that start hour.
  4. Set the meeting duration; rows turn green only when the whole slot fits inside working hours.

Technical Specifications & Standards

The mechanics matter for reading the table correctly. Each row is today's date at that wall-clock hour in your own timezone: the code converts that moment to an exact instant, then formats it in both selected zones via Intl.DateTimeFormat, so daylight saving is handled per-date and a row where one zone has switched shows the gap correctly. The rating scores the local hour in each zone at both the start and the last minute of the meeting (2 points inside 09:00-17:00, 1 point inside 08:00-19:00) and takes the minimum of the four, so 'great for both' genuinely means both parties are in business hours for the whole meeting. The leftmost 'your start' column is your own local start hour, and the two zone columns show what that moment is on each clock, so a row labelled 14:00 shows 14:00 in your zone. The table uses today's date only and has no date picker, so recheck a slot that falls after a DST change. This tool compares two zones only; for a wall of zones see the world clock.

Targeted Use Cases

  • Scheduling a recurring call between Europe and India across a DST change.
  • Finding the least-painful slot for a call with the US West Coast from Asia.
  • Negotiating interview times with a candidate in another hemisphere.
  • Planning a launch moment that lands in working hours for two offices.

Notes & Gotchas

  • Read the per-zone time columns for the actual clock times: the leftmost column is your own start hour and the guest column shows what that is there.
  • Accept amber 'workable' rows when no green row exists — some zone pairs have none.
  • Recheck the chosen slot the week after a DST transition in either country.
  • Agree the time in a written zone-qualified form (with both local times) to avoid off-by-one errors.

Frequently Asked Questions

Which hour does the first column show?

It is your own local start hour for that row. The next two columns show the same moment on your clock and on your guest's clock. Always schedule from those columns.

How is each row rated?

Each zone scores 2 if its local hour falls in 09:00-17:00, 1 if it falls in 08:00-19:00, and 0 otherwise, checked at both the start and the last minute of the meeting; the row shows the lowest of the four scores as great, workable, or unsociable.

Does it handle daylight saving time?

Yes. Each row's moment is formatted through Intl.DateTimeFormat with the current date, so each zone's DST rules apply per row. Rows near a DST changeover show the shifted offset correctly.

Can I compare more than two timezones?

Not in this tool — it is built for the common two-party case. To survey a whole team's zones, use the world clock tool to see business-hour highlights across many zones at once.
