Catholic Calendar instructions
Everything on this page refers both to the iPhone and the iPod Touch. There is no difference between the two devices as far as this program is concerned.
Views
The calendar view shows you an extract from the liturgical calendar:

The page view shows you one particular page for your chosen day:

The calendar view
This lets you view and scroll through the liturgical calendar.
To go to the page view for a particular date, tap on that date.
Going to a different year
If you scroll to the top of the calendar, you will see a line saying "Previous year". Tap on this to go one year back. At the bottom of the calendar you will find a line saying "Next year". Tap on this to go one year forward.
Going to a specific date
Tap the Pick button to bring up the standard iPhone date picker.
Coming back to today
If you have been exploring the calendar and want to get back to today quickly and easily, tap the Pick button, and underneath the iPhone date picker you will see a button marked Today.
Using a different local calendar
Different parts of the world have their own local calendars, with variations from the basic General Calendar. To change calendars, tap the "i" symbol at the bottom left of the screen and select "Local Calendars" from the menu that appears.
The page view
Scrolling
You can scroll the text by dragging it, just as with any other iPhone program.
Zooming
You can zoom in and out using the same pinch-zoom technique that works in Safari and other iPhone programs.
You can also double-tap on the text display to enlarge the text. After enough double-taps, the text goes back from large to small.
A quick shortcut back to the standard text size is to triple-tap on the text display.
Viewing different dates
Tap the Dates button to go to the calendar view.
Viewing different pages
You can see the calendar and the About Today page for any date at all.
As far as other pages are concerned, you can view them if you are connected to the Internet, and only for yesterday, today and tomorrow. Tap the Hours button on the top right to switch between Mass readings, the Invitatory Psalm, Morning Prayer, the three daytime hours (mid-morning, midday, and afternoon), Evening Prayer, Night Prayer, and the Office of Readings.
If you find these limitations inconvenient, buy the Universalis application, which is unrestricted and never requires an Internet connection.
Bible versions
The scripture readings all use the Jerusalem Bible translation. If you buy the Universalis application, you will also have the option of the New American Bible translation for the readings at Mass.
