How does the Golden Overlap Window finder work?

The algorithm evaluates all 24 UTC hours against the configured local offsets of your team members. Hours where all participants fall within Core Working Hours (09:00 - 18:00 local time) are flagged as Golden Windows. If no perfect overlap exists, it highlights acceptable shoulder windows (07:00 - 21:00).

How does this tool handle fractional timezones like India (IST)?

The engine fully supports fractional hour offsets (such as India Standard Time UTC+5:30 or Adelaide UTC+9:30), correctly rendering exact 30-minute intervals and local clock times.

Does Daylight Saving Time (DST) affect the overlap?

Yes. Different countries transition into and out of Daylight Saving Time on different dates (e.g. US in early March vs Europe in late March). Use the offset presets or custom offset inputs to match your current seasonal timezone.

Can I copy the meeting times into Slack directly?

Yes. Click 'Copy Slack Announcement' to copy a formatted markdown list indicating the local time and core/shoulder/sleep status for every team member.

Is any team data saved or uploaded to external servers?

No. The entire matrix and overlap algorithm runs 100% client-side in your web browser. Zero team locations or meeting details are transmitted over the network.

What should we do if our team has 0 hours of overlap?

For teams with extreme timezone dispersion (e.g. US West Coast and East Asia), live overlap often forces someone to join late at night. Best practice is either rotating meeting times weekly so the burden is shared fairly, or shifting status updates to asynchronous written memos in Slack or Google Docs.
