## Whenr Whenr Description
Doing math with dates and times is hard.  Whenr Whenr makes it easy, with a simple calculator-style interface for dates, times, durations, and unit conversions.  There are no awkward forms, no modes to switch between, and no workflows to learn.  Just type in your values, select the function you want to apply, and get your answer. 

With Whenr Whenr you can:

- Answer time questions quick and easy.  For example, calculate “how long is it from now until 7:42?” or “what time will it be in 4 hours and 47 minutes?”?

- Count days between dates, add weeks to a date, or work across months without manually counting.

- Make schedules easier to reason about.  Figure out equal turns, manipulate durations, split time fairly, and keep plans running smoothly.

- Make weird durations readable.  Convert amounts like 400 hours into weeks, 5,000 minutes into days, or 10,000 seconds into hours, so you can actually think about them. 

And it does all this in a familiar calculator-style interface - not a maze of tabs and dropdowns.  There's no mode switching, no confusing forms, and no translating your question into an app's weird logic. You just enter dates and times using the keypad and get the right answer fast.
