This At-A-Glance calendar I like!  I can make notes of upcoming events, and organize tasks on it, as well as make quick calculations.  Somebody I know even used it simply as a notepad.

On this date, I am still transitioning into the New Year.  Somehow this year, I am finding it easy to write 2016 in the date, instead of 2015.

Here is another kind of calendar from Calendarpedia, which can be nicely used as a checklist.  Happy New Year everybody!
