DateInTray is a small freeware utility that displays the date in the Windows tray.

The day of the month is displayed in the DateInTray icon, and the entire date can be seen in a tooltip popup by holding the mouse cursor over the icon.

A useful popup calendar can be brought up by clicking on the DateInTray icon. This easily accessable calendar popup is very useful when you need to quickly reference a calendar.

The calendar popup automatically shows the current date, and include arrow buttons to easily view next and previous months.

DateInTray can be easily added to the Startup folder in the programs menu so that it automatically starts every time you log in.
