The site loads quickly. It's fast with few ads.

Maybe the date command can do things like calculate the number of business days between two dates, accounting for U.S. holidays, and add or subtract work days excluding U.S. holidays -- I don't know. But I know it would take more effort than I'm willing to do to figure that out and test it. And I suspect it would involve a few switches and be subject to easy error.

For pulling up the calendar, it's literally a bookmark that brings up a browser tab with the year's calendar, showing U.S. national holidays. Can the cal command show holidays at all? It's unclear.

I think it's a bit sad to discount the value of a clear, usable, and fast GUI over a command-line interface for certain day-to-day tasks. Both tools have their uses.
