Main features

no dependencies to other libraries
currently localized languages
datepicker
date range picker
popup mode
inline mode
supports keyboard
supports RTL
animation of calendar (open/close)
awesome configuration possibilities
- easily set styles to the component which are in line with your page theme
  - calendar
  - input box and input box controls
- 50 options
  - change value of any option dynamically
well tested
- coverage report
- most of the code is from existing libraries which are widely used
