Used Count-- for Windows?
Developer’s Description
Count is a countdown program which can display a realtime countdown to any date starting from 1750s and ending at a high year limit as 9900s. The program window displays the countdown with a refresh interval which you can set between 1/20 of a second and a second. You can select any combination of all the basic time units from milliseconds to years, including hours, weeks, months, days, minutes and seconds, for the countdown.
You can set significant digits of the values shown and even organize how significant digits look by limiting long, eye-disturbing values. You can save presets for any time you want, as many as you want. You can export these presets to a file and of course import the preset files. Version 1.0.0.2 may include unspecified updates, enhancements, or bug fixes.
