Frequently Asked Questions
Common questions about Intl DateTime Calendar
No. Only the text a visitor reads changes. Every date is stored exactly as WordPress stored it. You can switch calendars whenever you like. Removing the plugin puts everything back the way it was.
No. Each date keeps its machine readable HTML datetime value in the Gregorian calendar. Search engines read this value. Only the wording a person sees is converted.
Yes. Dates in the Date block, Query Loop, comments and archives are all covered. This includes any custom format set on an individual block.
Yes. <?php if ( function_exists( 'intl_datetime_calendar_format_date' ) ) { echo intl_datetime_calendar_format_date( '2026-08-19' ); } ?> You can pass a date string, a Unix timestamp or a DateTime object, and a second argument to choose the format. Or use the shortcode in your content. [intl_datetime date="2026-08-19" type="date"]
Yes. On a multilingual site each language can have its own calendar, so a Thai reader sees Buddhist years while an English reader on the same site sees Gregorian ones. Use the intl_datetime_calendar_calendar filter to set this up.
Only dates on their way to a page are converted. Scheduled jobs, REST and AJAX requests, feeds and the admin are left alone, so anything another plugin stores or compares stays Gregorian. If you still need to exclude something, use the intl_datetime_calendar_should_convert filter, or turn off server rendering on the settings page.
No. Only dates on their way to a page are converted. A plugin that stores a date, compares one, or formats one during a scheduled job gets the ordinary Gregorian value. If you write a plugin, prefer current_datetime() or get_post_datetime() for anything you intend to store, since those are not display functions in the first place.
It is a standard PHP extension that most hosts already provide. You do not strictly need it. However, with it, your dates are written before the page is sent instead of in the reader's browser. This is faster and works without JavaScript. Site Health tells you whether you have it.
