Quick Month Calendar adds a tiny calendar pop-up to the clock icon in your Windows XP tray. Just hover your mouse over the clock and up it pops, ready to serve. That’s it. Nothing more dramatic. But definitely a bit useful.
QuickMonth Calendar is a freeware program which displays a small calendar on your Windows desktop whenever your mouse hovers over the clock in the system tray. The calendar display may also be toggled on and off by using the Windows+Q keyboard shortcut or a different key combination that you specify.
