Usage

Date Range with Time

echo IndieWeb\DateFormatter::format('2013-10-08T07:00:00-07:00', '2013-10-08T17:00:00-07:00');

outputs

<time class="dt-start" datetime="2013-10-08T07:00:00-07:00">
  October 8, 2013 from 7:00am
</time>
to
<time class="dt-end" datetime="2013-10-08T17:00:00-07:00">
  5:00pm (-0700)
</time>

(whitespace added for readability)

which displays in a browser as

October 8, 2013 from 7:00am to 5:00pm (-0700)

Date Range with No Time

echo IndieWeb\DateFormatter::format('2013-10-08', '2013-10-11');

outputs

<time class="dt-start" datetime="2013-10-08">
  October 8
</time>
-
<time class="dt-end" datetime="2013-10-11">
  11, 2013
</time>

which displays in a browser as

October 8-11, 2013

Other Examples

This example shows how progressively more data is added to the output as the start and end dates have less in common with each other.

use IndieWeb\DateFormatter;

echo DateFormatter::format('2013-09-03', '2013-09-08');
// September 3-8, 2013

echo DateFormatter::format('2013-09-28', '2013-10-03');
// September 28 through October 3, 2013

echo DateFormatter::format('2013-12-30', '2014-01-02');
// December 30, 2013 through January 2, 2014

Here are similar examples when the dates include times as well.

use IndieWeb\DateFormatter;

echo DateFormatter::format('2013-10-08T07:00:00-07:00', '2013-10-08T17:00:00-07:00');
// October 8, 2013 from 7:00am to 5:00pm (-0700)

echo DateFormatter::format('2013-10-08T07:00:00-07:00', '2013-10-10T17:00:00-07:00');
// October 8, 2013 at 7:00am until Oct 10 at 5:00pm (-0700)

echo DateFormatter::format('2013-08-31T07:00:00-07:00', '2013-09-01T17:00:00-07:00');
// August 31, 2013 7:00am until September 1 at 5:00pm (-0700)

echo DateFormatter::format('2013-12-31T07:00:00-07:00', '2014-01-01T17:00:00-07:00');
// December 31, 2013 7:00am until January 1, 2014 5:00pm (-0700)

Alternate Class Names

If you want the HTML to include Microformats classes other than "dt-start" and "dt-end", you can pass class names as additional parameters.

echo IndieWeb\DateFormatter::format('2013-10-08T07:00:00-0700', '2013-10-08T08:50:00-0700', 'dt-departure', 'dt-arrival');
<time class="dt-departure" datetime="2013-10-08T07:00:00-07:00">
  October 8, 2013 from 7:00am
</time>
to
<time class="dt-arrival" datetime="2013-10-08T8:50:00-07:00">
  8:50am (-0700)
</time>

Tests

Please see the tests for more complete examples of different output formats.

Future Enhancements

  • Optionally also display the day of the week in date range output
  • Option to use short month names instead of full names
  • Make the parser more tolerant of other input formats

If you see other input or output formats you would like handled, please open an Issue with a description. Bonus points if you write it as a test case:

  public function testDescriptionOfWhatYoureTesting() {
    $this->_testEquals('Final Text Output', 'start-date', 'end-date');
  }
