How can I make a calendar event repeat on an irregular schedule?

Start with the dates, not the calendar’s repeat menu. Write down the next several actual occurrences you expect, including any known skipped dates or changes. Then ask whether those dates follow one clear rule you can explain in a sentence. For example, “the first and third Wednesday” may describe a pattern; “March 4, March 19, April 2, and April 23” may not.

If you are using Google Calendar on a computer, its guidance describes creating or editing an event, opening “Does not repeat,” choosing a frequency and an end point, and saving. [S1] That describes the general recurrence setup, not a guarantee that your exact pattern is available. Check the choices in the calendar you actually use before entering a long series. Calendar products and platforms may offer different options. [S1]

Separate the predictable part from the exceptions. If the calendar offers a rule that correctly creates the regular dates, you can consider using a repeating series for that baseline and handling unusual dates separately. Before saving, inspect the dates the series produces, if your calendar allows it; compare them with your written list rather than assuming the rule fits.

For example, suppose an event usually occurs every other week, but several dates are shifted around holidays. Treat “every other week” as a candidate rule, not a guarantee about what your calendar can represent. Confirm the generated dates and decide how to handle each shift using the controls available in that product. The Google Calendar guidance does not explain how to edit individual occurrences or exceptions, so verify those controls in the product’s own help before relying on them. [S1]

Use separate entries when the dates do not fit a recurrence option you can confirm, when dates change often, or when a single series would make it hard to tell which occurrence is correct. A recurrence rule is convenient only when it reliably represents the schedule you intend. For a short list of irregular dates, separate events can be easier to inspect and correct.

A worked example: assume a group meets on June 3, June 17, July 8, and July 29. Those dates do not form an obvious weekly or monthly sequence. Unless your calendar offers a rule you can verify against all four dates, create four individual events. Give them the same clear title and, if useful, a short note such as “part of the activity schedule.” That keeps the entries recognizable without implying that a repeat rule will produce later dates correctly.

Before relying on the schedule, compare the calendar view with your written list: check the first few dates, any known exceptions, and the intended final occurrence. Google Calendar’s computer guidance says a repeating event can be given an end point and is limited to 730 occurrences. [S1] That limit does not tell you whether your particular irregular schedule is supported or how other calendar products behave. If you cannot confirm the rule or end point, use individual entries or consult the help for your specific calendar and platform.

A reusable check: write the intended dates first; confirm the recurrence choices available in your calendar; inspect generated dates against your list; set and verify an end point if using a series; then revisit the calendar after saving. For separate entries, check that every intended date appears once and that no unwanted dates were added.
