Two figures in, a clear answer out. The date to date calculator uses choice, end date and start date to produce time between these two dates is.., result seconds and dog years, applying the standard relationship for this problem in the order the calculation actually needs it.
What Is the Date to Date Calculator?
The date to date calculator turns choice, end date and start date into time between these two dates is.., result seconds and dog years.
It is a quick way to get from the numbers you have to the number you need, without setting up a spreadsheet or reaching for a formula.
How the Date to Date Works
Each result follows from the ones before it, and the calculator shows every step, so a surprising answer can be traced back to the input that caused it.
Round your inputs to the precision you actually know, and keep more precision than that in the intermediate steps.
Getting a Result You Can Trust
Run the calculation twice with slightly different inputs. A sensible calculator moves its output in proportion; a wild change points to a unit or a decimal point problem in what you entered.
Write the inputs down next to the answer. It takes a moment and it is the difference between a number you can explain and one you cannot.
A Worked Example
Working through an example, with choice set to 1, end date set to 10, start date set to 5, the calculator returns time between these two dates is.. of 51, and result seconds of 51, and dog years of 357. Substitute your own figures and the same steps produce the same kind of answer.
Frequently Asked Questions
What do I need to work out time between these two dates is..?
Enter choice, end date and start date. The calculator then works through the relationship and reports time between these two dates is.., result seconds and dog years.
What does the date to date actually calculate?
It takes choice, end date and start date and converts them into time between these two dates is.., result seconds and dog years using the standard relationship for this problem. Each step is applied in turn, so every output is traceable back to the numbers you typed in.
How should I enter choice?
Use the value you actually have, in the unit shown next to the field. Enter every value in the same unit system. The calculator assumes the figures you supply are consistent, so it cannot correct a mistake that happens before the calculation starts.
Why does a small change in one value move the answer so much?
That happens when an output depends on a ratio, because dividing by a small number magnifies any change in it. Check the units first, then check whether the value you entered is in the range the relationship was designed for.
Is the answer exact?
It is as exact as the formula and the inputs allow. The method itself is the standard one for this problem, so the only sources of error are the figures you enter and the precision you ask for.
