It supports both Gregorian and Jalali (Persian) calendars, offers single date and range selection modes, and includes features such as time picking, input masking, and RTL (Right-to-Left) layout support.

- Customizable date and time formats
- Responsive and accessible UI with animation support
- Extensive configuration options for styling, placement, and behavior
