Timesheet.js

Ooh, this is definitely something I'm going to use for quick timeline-based project meetings.

It's called Timesheet.js and enables you to quickly generate a timesheet with just an array events:

new Timesheet('timesheet-default', 2002, 2013, [  
  ['2002', '09/2002', 'A freaking awesome time', 'lorem'],
  ['06/2002', '09/2003', 'Some great memories', 'ipsum'],
  ['2003', 'Had very bad luck'],
  ['10/2003', '2006', 'At least had fun', 'dolor'],
  ['02/2005', '05/2006', 'Enjoyed those times as well', 'ipsum'],
  ['07/2005', '09/2005', 'Bad luck again', 'default'],
  ['10/2005', '2008', 'For a long time nothing happened', 'dolor'],
  ['01/2008', '05/2009', 'LOST Season #4', 'lorem'],
  ['01/2009', '05/2009', 'LOST Season #4', 'lorem'],
  ['02/2010', '05/2010', 'LOST Season #5', 'lorem'],
  ['09/2008', '06/2010', 'FRINGE #1 & #2', 'ipsum']
]);

Which results in:

Timesheet.js

Or as Timesheet puts it:

Visualize your data and events with sexy HTML5 and CSS3. Create simple time sheets with sneaky JavaScript. Style them with CSS and have mobile fun as well.
