The date field can be displayed, or formatted, several ways, some configurable in the date settings, others that are automatically provided as options.

You'll see these formatters as options on the 'Display fields' screen and when you add the fields to Views. You can also use these formatters in custom code by doing something like:

    print content_format('field_date', $node->field_date[0], 'iso');

### Formatter settings

In many places you can further control the way multiple value dates will be displayed with formatter settings. The formatter settings look like:

Show value(s)
starting from
ending on

The number of values should be a numeric value, or blank to show all dates that match your other options. 'Starting from' and 'Ending on' can be a fixed dates in ISO format (like 2009-03-03T10:30:00) or relative times like 'now' or 'now +1 day'.

### Formats and Format Types

Formatter options include:

default
  The main way to display this date, configured in the Date settings, defaults to the site short format.

  The site short format.
medium
  The site medium format.
long
  The site long format.
time
  Display the date time only, using the time format in the default display.
time_timezone
  Display the date time and timezone, using the time format in the default display.
iso
  Display the date in the standard ISO format of YYYY-MM-DDTHH:MM:SS.
ical
  Display the date in the standard iCal format of YYYYMMDDTHHMMSS.
timestamp
  Display the date as the Unix timestamp value.
format_interval
  Display the date as 'XX days, XX hours ago' or 'XX months, XX days from now'.

To set up custom formats and formatters, go to admin/settings/date-time/formats. You can either use a pre-configured display format, or create your own formatters and formats. Define a php date format string like 'm-d-Y H:i' (see http://php.net/date for more details on custom format strings.)
