We'll create fresh WordPress site with Arabic-Indic Numerals for Arabic WordPress installed. You have 20 minutes to test the plugin after that site we'll be deleted.
This plugin simply replaces Arabic numerals (a.k.a. Hindu-Arabic numerals or Indo-Arabic numerals) with Eastern Arabic numerals (a.k.a. Arabic–Indic numerals or Arabic Eastern numerals) in the date of posts or comments on WordPress. This is useful on sites using the Arabic version of WordPress, which translates month names but leaves the numbers unchanged.
