Jalaliday-forked

This is a fork of the Jalaliday plugin for the awesome Day.js.

This package should be considered a temporary solution until some fixes are applied to the original project. I just need this package in the meanwhile :D

Please note that this package will be deprecated whenever the main package fixes the issues that are fixed here. So keep an eye out.

The rest of this page is the original README in the time of fork.
