# DaySpan

A date & schedule library to use for advanced calendars in TypeScript and JS.

- [Google Calendar Clone](https://clickermonkey.github.io/dayspan-vuetify/example/) checkout [dayspan-vuetify](https://github.com/ClickerMonkey/dayspan-vuetify)
- [Documentation](https://clickermonkey.github.io/dayspan/docs/)
- [Download JS](umd/dayspan.js)
- Install via `bower install dayspan` or `npm install dayspan`

### Features

- Schedules track how frequent events occur using 20+ properties
- Events can last minutes, hours, days, or weeks
- Events can occur all day, or 1 or more times during the day
- Events can have any day & time included as an event occurrence (they don't need to match the frequency of the schedule)
- Events can be excluded, cancelled, or have metadata (specific event occurrence, all in a given day, week, month, quarter, or year)
- Event occurrences can be moved
- Calendars can represent a span of days, weeks, months, or years
- Easily list the next/previous days that occur on a schedule
- Describe a schedule in a human friendly string
- Export and import schedules and calendars to plain objects for easy saving and loading
- Provides logic to help display intersecting events on a calendar

### TypeScript Example

```typescript
// A monthly calendar around today (string=event data type, any=schedule metadata type)
let cal = Calendar.months();

// Every Monday 9:00 - 9:30
cal.addEvent({
data: 'Weekly Meeting',
schedule: {
dayOfWeek: Weekday.MONDAY,
times: 9,
duration: 30,
durationUnit: 'minutes'
}
});

// Dr. Appointment on 01/04/2018
cal.addEvent({
data: 'Dr. Appointment',
visible: false,
schedule: {
on: Day.build(2018, Month.APRIL, 1)
}
});

// Mother's Day
cal.addEvent({
id: 'someUserProvidedId',
data: "Mother's Day",
schedule: new Schedule({
weekspanOfMonth: 1, // 2nd
dayOfWeek: Weekday.SUNDAY, // Sunday
month: Month.MAY // of May
})
});

// The array of days in the month, each day has a list of the days events.
cal.days;

// Go to the next month
cal.next();

// Select this day and update the selection flags in the calendar days
cal.select(Day.build(2018, Month.APRIL, 12));

// Remove the schedule
cal.removeEvent('Weekly Meeting');

// A weekly calendar with custom MyEvent class
Calendar.weeks();

// A daily calendar covering 3 days centered on today
Calendar.days(3);

// A daily calendar covering 3 days starting with given date
Calendar.days(3, Day.build(2018, Month.JUNE, 15), 0);
```

### JS Example

You just need to append `ds` to the beginning of the classes:

```javascript
// A monthly calendar around today
var cal = ds.Calendar.months();

// Every Monday 9:00 - 9:30
cal.addEvent({
data: 'Weekly Meeting',
schedule: {
dayOfWeek: [ds.Weekday.MONDAY],
times: 9,
duration: 30,
durationUnit: 'minutes'
}
});

// Dr. Appointment on 01/04/2018
cal.addEvent({
data: 'Dr. Appointment',
schedule: new ds.Schedule({
on: ds.Day.build(2018, ds.Month.APRIL, 1)
})
});
```
