WTH isn't there an easy way to format and/or manipulate dates (without jinja)?

Seems like nearly half of the templating questions on the various forums (here, FB, reddit) surround dates. Probably not that much, but it’s way up there.

SOOO many people spend so much of their time, and the time of others to help them, to figure out simple things like date format, or getting “tomorrow.”

Templates are powerful - but I’d argue also over-relied on. There must be a better way if the goal is to improve usability.
