Hi Sagi,
Thanks for contacting Syncfusion support.
We are providing more than 350 culture specific files to localize the date in our control including the Hebrew language. You have to set the ‘locale’ property value as ‘he-IL’ and include the same culture script file (globalize.culture.he-IL.min.js) or refer globalize.cultures.min.js which includes all culture files. We have attached a sample in the following location to showcase the solution, so please refer to it.

If still you face difficulties, please revert back the sample based on your application. This would be helpful for us to analyze more about your problem and provide a solution at the earliest.
Regards,
Saravanan A J
