Thanks to Mehdi Ahmadizadeh, the new versions work fine with current Google Calendar UI. Also some ideas from Shayan have been implemented.
Here are latest features (for version 2.4):
- The userscript is now available in two editions: English and Persian. Using Persian edition gives you Persian numbers and months' names;
- The font of Persian texts in Persian version is bigger than the default texts;
- The name of the Jalali month is shown in the first day of the month (in the table).
