WinDay is a fast, small calendar program developed for use in Windows 95/98/ME/NT/2000. In a single screen, this program gives the current (system) date and time, and some information of interest for that day, such as that encountered in an almanac. The information given (besides time and date) includes: anniversaries, moon phase, sunrise and sunset; if applicable for that day, religious observances, astronomical events and special messages are indicated. A thought for the day is also given. The user can also move to other dates, and see, for example, future occurrences.
