I often want a simple terminal-based world clock for scheduling. I finally scratched my itch and wrote a little script using Python’s awesome pendulum library.

You can specify a time (using any string that pendulum can parse) or let it use local time. And unlike the bash script I had found and been using for a few years, it properly tracks day shifts across timezones. (This need arose from scheduling with folks in India.)
