How WhenItWorks works.

Five minutes from idea to link.

1

Create your event

Give it a name, add an optional description, and choose which dates might work. Set the daily time window using a slider — e.g. 9 AM to 6 PM. Takes under a minute.

2

Share the link with your group

Copy the event URL and send it to everyone — over chat, email, or however you communicate. Organizers and participants use the same link. There is no separate admin view.

3

Everyone marks when they're free

Each person opens the link, enters their name, and taps or clicks the time slots that work for them. No login, no password, no account required. Works on any device.

4

See who's replied and the best times

After submitting, the page shows a live heatmap of group availability — how many people are free at each slot, color-coded by overlap. The best times are highlighted automatically.

5

Pick a time and share the decision

Use the heatmap to choose the slot with the most overlap. Let your group know via whatever channel you used to share the link. Done.
