Date coversion tool?

I’m a user of EEMS 10.3.5 version.
I need “date conversion tool” that can convert from Julian date to Gregorian date or vise versa.
This tool has been in the previous version(EE 8.4) but now I don’t know where this tool is.
Please let me know where it is.
Thank you.

Thank you for your question. We recently realized that this tool is missing and have already added it to EEMS10.4. This version is undergoing testing and should be ready for beta release in the next few weeks.
