To test your schedule, you can use the get_dates(n, start, end) function to retrieve the next n scheduled dates while optionally specifying the time window via start and end date.

Here is the code you may use:

import asyncio
from prefect.orion.schemas.schedules import CronSchedule


async def validate_schedule():
    schedule = CronSchedule(cron="*/5 * * * *", timezone="Europe/Berlin")
    response = await schedule.get_dates(10)
    print(response)


if __name__ == "__main__":
    asyncio.run(validate_schedule())
