Shows Time and Date in the right place value position.
Use Time Calculator to calculate the time subtraction between 2 dates: You can fix a date in the past and subtract it from the present time: You get the elapsed time. You can fix a date in the future and subtract the present time: You get the countdown to the fixed date. (Light gray dates are in the past; Light green dates are in the future)
Not available for dates earlier than 1582. (Due to the Gregorian Calendar)
Stopwatch and a countdown counter.

Practical applications proposed by users: -. Useful to calculate demurrage. (http://en.wikipedia.org/wiki/Demurrage) -. Useful for calculating maintenance times -. To calculate amount of pills of a medical treatment. -. Calculate the number of days, or hours, or minutes, or seconds, remaining until retirement. -. How old am I? -. How old are you? -. How many months, or weeks, or days, or hours, or minutes, or seconds are there in 1000 years?
-. Estimate the number of heartbeats throughout life at this time. - multiplying lived minutes by a number between 60 and 100 for human beings. - minutes, multiplied by 500 in the case of mice. - minutes, multiplied by 28 in the case of elephants. - minutes, multiplied by 6 in the case of the giant Galapagos tortoise.
-. Estimate the number of breaths made throughout life at this time: (for human beings) - birth to 6 weeks: 30–60 breaths per minute - 6 months: 25–40 breaths per minute - 3 years: 20–30 breaths per minute - 6 years: 18–25 breaths per minute - 10 years: 15–20 breaths per minute - adults: 12–20 breaths per minute
