APScheduler

Advanced Python Scheduler — schedule Python functions to run at specified times or intervals. Current stable version is 3.11.2. A completely rewritten 4.x is in pre-release with a different API (apscheduler.Scheduler instead of BackgroundScheduler, etc.) — 4.x is NOT installed by pip install APScheduler. Two concurrent stable lines: use 3.x for production. The 3.x vs 4.x API confusion is the #1 footgun.
