Display percentage of Days passed from the beginning of the current year

[lamyergeier]

Motivation: This is helpful for me as I am suffering from procrastination and it would be useful visual feedback!

Issue: Its difficult to imagine how many days have passed from the beginning of the year till today's date, just by looking at the date.

Solution: I have an idea that one could display percentage (with truncated decimal). For example if it it is Feb 5 of a year then 36 days out of 365 have passed and I would like to display 10%.
