Re: Checker question, sum of days between "hidden date" and today

Hello!
I'm not sure if this is the correct forum for this question, please redirect me if needed.

I have an idea of creating a series of Challenges where the requirements are to have logged any number of geocaches that totals the sum of days between "hidden date" and today equal to the orbital period of the different planets in our solar system.
Examples: Earth is 365 days, Mars is 687 days, Jupiter is 4332 days, etc.
My question is: Is it possible to create Challenge Checkers that checks the requirements above?

Thank you in advance!

It would definitely be possible. If I'm understanding correctly, wouldn't this be very easy though, e.g. for Earth, just finding one cache over a year old?

You're correct it would be easier for the closer planets. What about the outermost Neptune that has an orbital period of 60195 days, (164.8 years) ?

Ahh i see! Yep, this would definitely be possible, then. Here’s a similar example, I think, but with years if you’d like
