why not work with google fonts?? RTL fonts are limited
Hello @Good_Site, welcome to the Community!
I need to say that we don’t integrate Google Fonts into the widget directly for legal reasons (GDPR and stuff). However, we do allow to pull the font from the website if you choose the first option in the Font setting – Default (Apply from Website).
We also applied a special CSS code to your Event Calendar, and the texts look neater now with the RTL. Please check it out now and let me know if you like it better 
And if you need us to make alterations or set a font from the Google Fonts for your widget, let us know. We’ll do our best to help
