Whoa, this is exactly an idea I had for Timeslot, the day planner app I posted on HN yesterday. Nice job, you beat me to it :)

It's a good idea, and this is a great start. Things that would make this invaluable:

- The ability to combine multiple schedules together to find free time overlaps (so that, for example, three people can find a good time to meet during the week)

- User accounts, so users can search for their friends by name and schedule meet ups

- Ability to extend before 6am and past 9pm at the click of a button
