EldoS TrayDays

From EldoS Corporation:

TrayDays is a small freeware tool, that shows you current date and configurable easy to use calendar. When you work, it looks like a tray icon, showing current day and month. But let's move mouse cursor over this icon... A calendar appears. This calendar can show week numbers, weekends and holidays. To configure the calendar, right-click on the tray icon. Popup menu will appear, with Settings item in it. Select Settings and you will be able to set the week end days and manage holidays.

TrayDays is intentionally made simple. It will be useful when you don't want to overload your computer with all those bells and whistles, that grapb computer memory and are hard to use.
