This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.

[TiSiE] RelativeTime


Adds template tags to your wordpress blog that lets you show relative time strings,
such as “3 months and 2 days” or “4 months, 10 hours and 2 minutes”.

Unlike other algorithms used to calculate relative time, this plugin uses an algorithm based
on written substraction and therefore the calculated relative time is synchronous to the gregorian
calendar system.
Example: Let’s assume todays date were “2010-03-01” and the post date were “2010-02-01“. The
result of this plugin’s calculation would be “1 month“.

Currently only englisch and german localizations are available. But maybe you can help me
translate to other languages. I will gladly add them. (see “FAQ” for more details)

The following template tags are available

  • the_date_relative / get_the_date_relative
  • the_modified_date_relative / get_the_modified_date_relative
  • comment_date_relative / get_comment_date_relative

Additionally there are two filter hooks available

  • tirt_get_string
  • tirt_get_array

Please see the “Other Notes
tab for more information about the usage.

Du kannst auch auf deutsch lesen.

This is a BETA release

So, if something is not working as expected or you get others errors or you encounter incompatibilities to other
plugins – please report them to me so I can fix and improve my plugin.



All template tags accepts one optional parameter which specifies how many
relative time string parts should be in the string. This parameter must be
an integer between 1 and 7 inclusively.

The default value is 2.

To prevent strings like “1 year, 3 hours and 2 minutes, parts that have the value 0
and all following parts are stripped from the string, regardless of the value of
the optional parameter.

– the_date_relative(1)

“1 year”, “3 days”

  • the_date_relative(3)

    “1 year, 2 months and 4 weeks”, “12 days, 3 hours and 37 minutes”, “4 days”

Filter Hooks

On general information how to use filter hooks, please see the
Funtion Reference

  • tirt_get_array

    applied to the date array at the end of tirt_get_array.
    Can be used to modify the values of the array.

    NOTE: The filter using this hook MUST return an array with the same
    keys as the input array.

  • tirt_get_string

    applied to the relative time string.
    Can be used to i.e append or prepend text to the string, If you do not want
    to do that on every occurence of the template tag in your theme files.


  • Relative comment date string on my blog


  1. Upload the .zip file to your plugins folder and unzip
  2. Activate the plugin through the plugin management admin interface
  3. Add the template tags to your theme files (see “Usage”)
  4. (Optional) Uses the filter hooks to modify the output without touching the
    plugin files.

There are no settings for this plugin, it will work straight away.


How do I translate to other languages?

Just take the “tirt.pot” file located in the subdirectory “translations” under the plugin’s root directory and add
the translated string in the “msgstr” line between the ‘”‘.
Save the edited file as “tirt-[langCode].po” and convert it to a .mo file with gettext.

Or use poedit: Load the tirt.pot file as new catalog, translate the strings and
save it as “tirt-[langCode].po”, poedit will automatically create a .mo file.

[langCode] is the language code, such as “en_EN” or “de_DE”.
