I am trying to do a javascript code that is able to handle huge dates. The date year might be higher than the max possible int.

I don't need hour, minutes, second and milliseconds from the current javascript Date object, just number of days.

I have been searching for libraries which might offer this possibility but I did not found any :(

I also looked at this answer: How to use Date in Javascript for prehistoric dates?

But I would like the solution to work with future dates also. And some past dates might be bigger than the big bang

I hope that someone can help me with this issue :)
