Settings » Date and Time Settings
This guide covers how to change your site’s date and time settings.
Change Timezone
You can update the timezone to whatever makes the most sense for your site, but it’s generally best if this matches the timezone settings on your computer/phone. You can find this option in Settings → General.
Select the timezone from the drop-down list and then click Save Changes to apply the new time zone to your site.
Change Date and Time Format
Adjusting the Date Format and Time Format will change how dates and times appear on your website. To find this setting, go to Settings → Writing. In the Composing section, click on Date and time format to expand those options.
Select your desired format and then click ‘Save Changes’ at the bottom to apply the new format for all dates displayed on your site.
If you want to create a custom time or date format for your site, visit the WordPress.org page on formatting date and time.
