Advanced Recurrence
Pro - Advanced recurrence rules require Eventonomy Pro.
Free Eventonomy already handles simple repeats - daily, weekly, monthly, and yearly, with an interval, an end-after count or end-on date, and a plain weekday list on weekly events (see Recurring Events). Eventonomy Pro adds the calendar rules those simple patterns can't express: "the 2nd Tuesday of every month," "the last Friday," specific days of the month, and dates to skip.

- How the advanced engine expands your rule into occurrences
What Pro Adds
Free's basic recurrence covers frequency, interval, count, until, and a simple weekday list on weekly events only. Pro's full-rule engine adds everything beyond that:
| Rule | Example | Free | Pro |
|---|---|---|---|
| Specific weekdays (weekly) | Every Mon & Wed | ✓ | ✓ |
| Specific weekdays (monthly) | On Tuesdays each month | - | ✓ |
| Nth weekday of the month | 2nd Tuesday of every month | - | ✓ |
| Last weekday of the month | Last Friday of every month | - | ✓ |
| Day of the month | The 15th of each month | - | ✓ |
| Last day of the month | The last day of each month | - | ✓ |
| Skip dates (exceptions) | Repeat weekly, but skip Aug 5 | - | ✓ |
When Pro is active, its engine automatically takes over any event whose rule uses one of these advanced patterns; simple events keep using Free's engine unchanged.
Configuring an Advanced Rule
The advanced controls appear inside the event editor's Recurrence panel, directly below Free's basic frequency and interval fields. They show and hide based on the frequency you pick, so you only see the parts that apply.
On these days (weekdays)
For weekly and monthly rules, a row of weekday checkboxes (Mon - Sun) lets you pick the days the event lands on.
- On a weekly rule, checking Mon and Wed means the event repeats on Mondays and Wednesdays.
- On a monthly rule, the weekday selection combines with the position control below to build "nth weekday of the month" rules.
On the … (nth weekday of the month)
For monthly rules, the On the dropdown sets the ordinal position:
- First, Second, Third, Fourth, or Last.
Combine it with a weekday above to build the rule. For example, Last + Fri produces "the last Friday of every month," and Second + Tue produces "the 2nd Tuesday of every month."
Or day of month
Instead of a weekday position, a monthly rule can target a fixed calendar day with the Or day of month field (1-31). Enter 15 for "the 15th of each month." The engine also understands the last day of the month, so a rule can reliably land on month-end even in short months.
End after / end on date
Two fields bound the series:
- End after (occurrences) - stop after this many instances.
- Or end on date - stop on this calendar date.
Leave both blank to repeat up to the site's recurrence horizon (see Recurring Events for how the horizon and daily maintenance keep future dates ready).
Skip dates
The Skip dates field takes a comma-separated list of YYYY-MM-DD dates (for example 2026-08-05, 2026-09-02) that are removed from the series. Use it to knock a holiday or a one-off cancellation out of an otherwise regular schedule without breaking the rest of the pattern.
How Occurrences Are Generated
When you save the event, Pro's advanced engine expands your rule into individual occurrence rows in the evnm_occurrences table - the same materialized occurrences the calendar, RSVP counts, and per-date attendee lists use. The first date of the series (the event's start) is always included, even when it doesn't itself match the weekday or day-of-month pattern. Skip dates are removed, and the series is capped so a very long or open-ended rule can't run away.
Everything else about recurring events - how RSVPs work across a series, and how to update or cancel a single occurrence - works exactly as described for Free recurrence.
