Looking for a plugin that displays todays date from different calendars

For example, we like to have a small widget box on sidebar that shows today’s date (today is 5 March 2014) from the following calendars:

14 Esfand 1392
3 Jumada I 1435
3 Adar II 5774
2456722 (Julian day)

As an addition, if it can display:
2014, Week 09, Day 64, 301 days remaining

Thank you
