Use this calculator to add or subtract two or more time values in the form of an expression. An acceptable input has d, h, m, and s following each value, where d means days, h means hours, m means minutes, and s means seconds. The only acceptable operators are + and -. "1d 2h 3m 4s + 4h 5s - 2030s" is an example of a valid expression.

This hours calculator computes the number of hours and minutes between two times. A full version can calculate the hours between two times on different dates.

For example, you can enter 9:30 and then "30" in the minutes field to see what is 30 minutes from 9:30 (it is exactly 10:00 o'clock). Or enter 12:45 as initial time and then 45 minutes to make the add time calculator tell you what is 45 minutes from 12:45 (it's 13:30 or 1:30 PM).

Ten-codes, also known as 10-codes or ten signals, are code words used by many police officers to aid with voice communication. The codes were originally developed in 1937 to allow for brevity, clarity, and standardization of messages transmitted over radio channels.

By default, there are two (2) time input rows on the calculator which includes the hours, minutes, seconds and milliseconds. The first row is where you enter your base time (minuend) while the second row is the time you want to subtract (subtrahend).

Use this time and date duration calculator to find out the number of days, hours, minutes, and seconds between the times on two different dates. To add or subtract time from a date, use the Time Calculator.

Find the remainder when 10^ {400} is divided by 199? You can use Fermat's little theorem . It states that if n is prime then a^n has the same remainder as a when divided by n. So, 10^ {400} = 10^2 (10^ {199})^2. Since 10^ {199} has remainder 10 ... The continuum is \aleph_ {37}. n = 1011 appears to work.
