Calenderr is a simple hack to make the Calendar app icon always show today's date (day-of-month). The existence of calendar icons for each day (1-31) in the theme on the device lets suspect that this feature was either planned and then abandoned or that it will come built-in in some future firmware.


put calendarhack.conf in /etc/init/apps directory (see the comment inside)

put calenderr.sh in /home/user folder  (see the comment inside)

Or simply try this (verified) *deb  file !
