What is schedule?

Schedule is a small Python library for running functions automatically at set intervals. If you want a piece of code to execute every 10 seconds, or at 10:30 every morning, or every Monday at a specific time, this library lets you express that in plain, readable code rather than dealing with the complexity of system-level scheduling tools. The syntax reads closely to plain English. You write things like schedule.every().day.at("10:30").do(job) or schedule.every().monday.do(job), where job is whatever Python function you want to run. Time zones are supported, so you can specify a target time in a named zone like "Europe/Amsterdam." You can also pass arguments to your function and schedule jobs with a random interval within a range, such as every 5 to 10 minutes. Once your schedule is defined, you run a loop that repeatedly checks whether any scheduled tasks are due and runs them. The library has no external dependencies, adds no background processes, and keeps everything inside your Python program. It supports Python 3.7 through 3.12. The README is minimal and focuses on the code examples. Full documentation is at schedule.readthedocs.io. The project is inspired by an article called "Rethinking Cron" and by a similar Ruby library called clockwork. It is distributed under the MIT license.
