1. Tell us when you're free
Tick the days you work and set your hours. Split them if you like — mornings only on Wednesday, half day Friday, nothing at weekends. Add overrides for holidays and that week you're at a conference.
| Monday | 9:00am – 5:00pm |
| Wednesday | 9:00am – 12:00pm 1:00pm – 5:00pm |
| Saturday | Unavailable |
2. Share one link
You get an address like old.cal.com/yourname. Put it in your e‑mail signature, on your business card, in your Twitter bio. One link, forever — you never have to update it when your schedule changes.
3. They pick a time
Your visitor sees a calendar of your real free slots, shown in their time zone. They click a day, click a time, fill in whatever you ask for, done. No account, no password, no software.
4. It lands in your calendar
Both of you get a confirmation e‑mail with a calendar attachment. The event appears in your calendar within seconds.
- Cancel and reschedule links in every e‑mail — no account needed
- Two‑way sync, so a meeting booked elsewhere blocks the slot here
Requirements
Nothing to install. Cal.com runs in:
- Internet Explorer 6, 7 and 8
- Firefox 2 and 3
- Safari 3 and 4
- Opera 9 and above
This list has not been checked since 2009 and is now almost entirely wrong.
Ready?
It really does take about two minutes.
