Recuring task every X months

If you’re willing to tinker, I developed a workaround to achieve this functionality using Vikunja’s n8n community node to implement Vixie Cron patterns. For example, 0 12 1 1/3 * (minute, hour, day of month, month, day of week) would trigger at noon on the first of the month every 3 months. You can test other patterns at cron checker. It’s super flexible.

To implement, see Repeating tasks by day of week. If you try to implement and run into issues, please reply in that thread and I’ll do my best to help!
