Much like the iPhone's iPod area and Photos application, the Calendar application depends on the goodwill of your computer. Much of its heavy lifting is done with the aid of your Mac's or PC's calendar application and iTunes. Before examining just how heavy a load this is, I'll take a look at what you can do with Calendar without a computer's assistance.
Calendar is capable of displaying events in three views: List, Day, and Month. They're laid out like so.
Tap Calendar, and by default, you'll see this month's calendar, with today's date highlighted in blue. Other days maintain a gray, businesslike appearance. Tap another day, and it adopts the blue box, while the present day gains a deeper gray hue. To return to the current day, either tap it (if you're viewing the current month) or tap the Today button in the top-left corner of the screen. To move to the next or previous month, tap the Previous or Next arrow, respectively, next to the month heading. To scan ahead more quickly, tap and hold one of these arrows.
Any days on the calendar that have events appended to them bear a small black dot below the date. Tap a day with a dot, and the events for that day appear in a list below the calendar, each preceded by its start time (Figure 4.10). Tap an event in this list, and you're taken to the Event screen, which details the name and location of the event, its date, its start and end times, and any notes you've added to the event.
Figure 4.10 Month view with an event.
To edit or delete the event, tap the Edit icon in the top-right corner of the screen. Within the Edit screen, tap one of the fields to change its information. (I discuss these fields in "Creating events" later in this chapter.) To delete an event, tap the red Delete Event button at the bottom of the screen; then tap the Delete Event confirmation icon that appears.
Tap the Day view button, and as you'd expect, you see the day laid out in a list, separated by hours. The day of the week and its date appear near the top of the screen. To move to the previous or next day, tap the Previous or Next arrow, respectively. To scan back or forward more quickly, tap and hold the appropriate arrow.
Events appear as blue-gray bars in the times they occupy, and are labeled with the name of the appointment and its location (Figure 4.11). Just as with events in Month view, tap them to reveal their details; to edit them, tap the Edit button.

List view shows a list of all the events on your calendar, separated by gray bars. Each gray bar bears the day's abbreviated name (Fri or Mon, for example) and the month, date, and year of the event. The event's title appears just below, preceded by its start time. Once again, tap an event to view its details. Tap Edit to edit the event or delete it via the Delete Event button (Figure 4.12).

Creating events on the iPhone is simple. Just tap the plus icon in the top-right corner of the screen to produce the Add Event screen, where you'll find fields for Title & Location, Start & End, Repeat, Alert, and Notes. In more detail:
- Title & Location. The title of the event will appear when you select the event's date in Month view. Both an event's title and location appear in the Day-view list. And in List view, you see just the event's title. As with any other field on the iPhone, just type the entries and tap Save when you're done.
Start & End. The title is explanation enough. Just tap the Starts field, and enter a date and time by using the spinning wheels at the bottom of the screen (Figure 4.13). Ditto with the Ends field. If the event lasts all day, tap the All-Day On/Off switch.

- Repeat. You can create an event that occurs every day, week, two weeks, month, or year. This method is a convenient way to remind yourself of your kid's weekly piano lesson or your own wedding anniversary.
Alert. A fat lot of good an electronic calendar does you if you're not paying attention to the date or time. Tap Alert and direct the iPhone to sound an alert at a specific interval before the event's start time: 5, 15, or 30 minutes; 1 or 2 hours; 1 or 2 days before; or on the date of the event.
You can create two alerts per event—useful when you want to remind yourself of events for the day and need another mental nudge a few minutes before the event occurs. Regrettably, you can't change the alert sound; you can only turn it on or off in the Sound Settings screen.
- Notes. Feel free to type a bit of text to remind you exactly why you're allowing Bob Whosis to dominate your Thursday afternoon.
Your computer and your iPhone have a nice sharing relationship with regard to events. When you create an event on one device, it's copied to the other, complete with title, location, start and end times, alerts (likely called alarms in your computer's calendar program), and notes.
Unfortunately, the iPhone holds just a single calendar. Although you can ask iTunes to sync multiple calendars to the iPhone (if you're using a Mac, your iCal Work and Home calendars, for example), all events go into that one iPhone calendar. And when the iPhone syncs events back to your computer, you have to tell iTunes which calendar to put them in.
Quite frankly, deleting events by using the iPhone's interface is a pain in the neck. As I mention earlier in the chapter, you tap an event, tap the Edit button in the Event screen, tap the red Delete Event button at the bottom of the screen, and then tap Delete Event again. This is a very inefficient way to delete events, particularly lots of events that have expired. You're better off letting iTunes lend a hand.
To do so, plug your iPhone into the computer and then select it in iTunes' Source list. Click the Info tab, and configure the Calendars delete option to read Do Not Sync Events Older Than X Days, where X is the number of past days you're willing to keep expired events on your iPhone. When you next sync your iPhone, events that occurred more than X days before the current date will be removed from the phone (Figure 4.14).

If you'd like to delete multiple future events, delete them from your computer's calendar. When you sync your iPhone, the events will disappear from the iPhone's calendar as well.
