@afewbugs I had looked into this a while ago and from a technical perspective the WebCAL and iCalendar standards which are used by Nextcloud and many others support recurring tasks. However, support for it seems to depend on both the server and the client and many lack support for it. I'm not really sure why; I assume it's just difficult to implement and/or not enough people asked about it. But if you use the right client it should work with Nextcloud.

@afewbugs would love to see more support for recurring tasks! Blaming men for the lacking feature seems kinda weird though. I see a lot of seemingly male users willing to pay for this feature: https://help.nextcloud.com/t/repeating-tasks/225106/21. Have you tried implementing that yourself instead of demanding it from men? I guess many people also just have other ways to keep track of these things, such as recurring calendar events with notifications, alarms, reminder apps, or they're good at remembering them.
