8. Countdown Timer between Two Dates
While technically not a continuous countdown device, date duration calculators are great tools for quickly figuring out how much time is left to complete a project using today's date or an estimated start date along the critical path of the project.
Among the top online offerings is Timeanddate.com's free duration date calculator. Enter a start and end date and the calculator will return the remaining time left. A short cut button for today's date, a calendar pop-up, and month and year drop-down lists make it easy to enter dates.

9. Number of Days Timer

Type in the number of days and then use the plus or minus symbol to find the exact date on the calendar looking ahead or behind.
10. Alarm Countdown Timer
A countdown timer with an audio or pop-up alarm is an added bonus. SavantTools.com offers a nice choice with a personalized alarm message.

When your time has expired, a pop-up box appears with your message and a catchy arcade-style tune plays until you turn off the alarm. This timer is definitely an attention-grabber, so use sparingly around others.
