Timezone Overlap Planner for Remote Slack Teams

Find the best meeting windows for your distributed Slack workspace. Calculate timezone overlap, pain scores, and meeting fairness for teams across any time zone.

Distributed teams using Slack face a daily challenge: finding a meeting time that doesn't force someone onto a call at midnight. The further apart your team's timezones, the harder it gets β€” and a single bad call time repeated weekly compounds into real burnout.

How to use with Slack

1

Add your team

Enter each Slack teammate's timezone and working hours. Supports every IANA timezone.

2

Find your overlap window

The planner calculates the UTC hours where everyone is within their working day, highlights the least-painful slots, and scores each option 0–100.

3

Share via Slack

Copy the shareable link and paste it directly into your Slack channel. Everyone opens the same pre-loaded planner β€” no setup required.

Features

Pain score per meeting

Every potential time slot gets a discomfort score showing exactly how early or late each person would be working.

DST-aware scheduling

Automatic daylight saving time detection prevents the surprise slot shifts that hit teams spanning the US and Europe each spring and autumn.

Rotating fairness tracker

Track who has taken the uncomfortable early-morning or late-night slot over time, so the burden rotates equitably.

Instant shareable links

The entire team configuration is encoded in the URL β€” share it in any Slack channel, no account needed.

Frequently Asked Questions

  • Can I use this for Slack standups across North America and Europe?

    Yes. Add all your participants with their timezone and working hours, and the planner highlights the best UTC windows for a daily standup. The pain score shows how uncomfortable each option is for each team member.

  • What if our teams have no working hours overlap at all?

    The planner will show zero overlap and flag the team as async-first. You can still find the least-bad slot for occasional synchronous calls, or use the Follow the Sun view to understand your 24h coverage.

  • Does it handle half-hour timezone offsets like India (UTC+5:30)?

    Yes. All IANA timezones are supported, including UTC+5:30 (Asia/Kolkata), UTC+5:45 (Asia/Kathmandu), UTC+9:30 (Australia/Darwin), and others.
