Google Calendar's favicon (the icon in your tab on your browser) used to just display "31". Starting today, Google is rolling out a new feature: the favicon will now display the actual current date. Not a huge change, but one that makes it a little more useful. Just look at the browser tab and you can check the date.
It will be rolling out over the next few days, so don't worry if you don't have it yet.
This is the second update to Google products this week, with Google Docs now having Pagination and native printing from the browser.
