(recurrence rule) string, you can specify a start date using the DTSTART
property. While specifying the start date is optional, providing it can help clarify when the recurrence should begin, thereby improving the predictability and understandability of the schedule. Without a start date, the recurrence would begin from an undefined point, which might not always align with the intended schedule.
To add a start date, you can include DTSTART
followed by a date and time value at the beginning of your rrule
. For example, if you want the recurrence to start on January 1st, 2023, at midnight, you would write:
DTSTART=20230101T000000Z;FREQ=MINUTELY;INTERVAL=1;COUNT=10
Here's a breakdown:
- `DTSTART=20230101T000000Z`: Sets the start date to January 1st, 2023 at 000000 UTC.
- `FREQ=MINUTELY;INTERVAL=1;COUNT=10`: Triggers at minute intervals with a count of 10 occurrences.
This setup ensures that both the frequency and the timing of the occurrence are clearly defined. If you're using a tool or library that supports rrule
strings, you should integrate the date in this manner. If you want more concrete examples or handling within a specific library, let me know!rithy

, a great place to start is the iCalendar RFC 5545 specification, which includes detailed information on recurrence rules. However, for more practical examples and explanations, you might find the following sources helpful:
1. Python dateutil
library documentation: This library includes an rrule
module that allows you to work with recurrence rules using Python. The documentation provides examples of how to use rrule
in code. Check it out here: https://dateutil.readthedocs.io/en/stable/rrule.html
2. RRULE Tool: There are various online tools that allow you to experiment with rrule
strings and visually see the generated dates. A quick search for "online rrule generator" should direct you to some useful ones.
3. Prefect Documentation: Prefect is a workflow orchestration tool that may incorporate rrule
for scheduling tasks. While it's more specific to Prefect, it can provide context on how rrule
strings are used in orchestration tools. Let me know if you want more targeted resources for Prefect itself.
Feel free to explore these resources to gain a better understanding of how rrule
works and how you can apply it in your use cases! If you have more specific questions, I'm here to help.
