Recurring events generation

Event structure

  var newEvent = {
      title: 'My next birthday'
    , start: new Date(2012, 6, 18, 16)
    , end: new Date(2012, 6, 18, 23, 30)
    , allDay: false
    , frequency: 'year'
    , recurrence: {
          'end-by': {
              after: 4
            , type: 'never'
          }
        , every: 1
        , exceptions: ['07/18/2012']
      }
   }

Server-Side support

// add seed module
var Seed = require('./lib/seed');

var today = new Date();

// defines an event object
var myBirthDays = {
    title: 'Event Instances'
  , start: new Date(1977, 6, 18, 15, 30, 48)
  , end: new Date(1977, 6, 22, 15, 30, 48)
  , allDay: false
  , frequency: 'year'
  , recurrence: {
        'end-by': {
            type: 'never'
          , on: today
        }
      , every: 1
      , exceptions: []
    }
}

// creates a new seed Object passing event object and options
var Seed = new Seed(myBirthDays, {
    start: new Date(2000, 0, 1)
  , end: today
});

// generates ans retrieves all instances by period
var instances = Seed.getInstances();

for (var i = 0; i < instances.length; i++) {
  var Instance = instances[i];
  console.log(Instance.start + ': ' + Instance.getNumber() + ' years');
};

building client-side library

you can use 'make build' rule to building client-side library. The generated file will be saved in dist/calendar-tools.js
