I'd say that 'date' is the natural program to try for date manipulations. ;-)

GNU systems are very useful in scientific settings, IMHO adding full Julian date in the astronomical sense to 'date' further enhances this.

Hmm, the aspect of date conversion is interesting. In particular:

We already have bi-directional conversion between common and Epoch dates ('date +%s.%N' to convert to seconds since Epoch, and 'date -d @...' to convert Epoch back to common). So if we do add a conversion to Julian date output, we should also add a -d shorthand for conversion from Julian on input.
