Currently, we have many options to setup custom recurring tasks. But there's something that is missing. Example: "Mother's Day" in my country is on the 1st Sunday of May. This kind of recurrence is not possible to setup. In the same way that it's possible to setup recurrences like: "Weekly, every Wednesday" or "Monthly, every last Monday", it is also important to have options related to yearly recurrences (like "1st Sunday of May", 2nd Monday of November, etc.).
