What’s the Recurring Rule Generator? calendar tips

Updated Apr 9th, 2025 by Marissa Stone

Managing recurring events in digital calendars can be complex, especially when dealing with intricate schedules. To simplify this process, AddEvent offers a Recurring Rule Generator, a tool designed to help users create precise recurrence rules effortlessly. This article explores the concept of recurring rules, their applications, distinctions from event series, manual creation methods, and how to utilize AddEvent’s generator effectively.​

What Is a Recurring Rule?

A recurring rule, often referred to as an RRULE, defines how events repeat over time in a calendar system. It specifies the pattern of the calendar event’s recurrence, including frequency (daily, weekly, monthly, yearly), interval, specific days, and the length of time it will continue recurring for. By establishing an RRULE, calendar applications like Google Calendar or Outlook Calendar can automatically generate all future instances of a recurring event, ensuring consistency and accuracy in scheduling, and saving hosts from having to manually create and send ongoing event invitations.

Why Use a Recurring Rule?

Implementing recurring rules offers several benefits:​

  • Efficiency: Automates the creation of repeated events, saving time and reducing manual input.​
  • Consistency: Ensures that all instances of an event follow the same pattern, minimizing scheduling errors or confusion.​
  • Flexibility: Accommodates complex recurrence patterns, such as events occurring on the first Monday of every month or every weekday for a set period.​

For example, if you’re organizing a weekly team meeting every Tuesday at 10 AM for the next three months, defining an RRULE allows the calendar to automatically populate these events without the need to enter each one individually.​

How to Write a Recurring Rule Without a Generator

Manually creating an RRULE requires understanding the iCalendar standard format. An RRULE is composed of various components:​

  • FREQ: Frequency of the event (DAILY, WEEKLY, MONTHLY, YEARLY).​
  • INTERVAL: The interval between each occurrence (e.g., every 2 weeks).​
  • BYDAY: Specific days of the week the event occurs (e.g., MO for Monday).​
  • COUNT: Number of occurrences.​
  • UNTIL: End date of the recurrence.​

For example, to create a rule for an event that occurs every Monday and Wednesday for 10 occurrences, the RRULE would be:​

FREQ=WEEKLY;INTERVAL=1;BYDAY=MO,WE;COUNT=10

Manually crafting such rules can be challenging and result in user error, especially for complex patterns, which is why we built a free RRULE generator so you don’t have to!

How to Use AddEvent’s Recurring Rule Generator

AddEvent’s Recurring Rule Generator simplifies the creation of RRULEs through an intuitive interface. Here’s how to use it:​

  1. Access the Generator: Navigate to AddEvent’s Recurring Rules generator.
  2. Define the Recurrence Pattern:
    • Repeat Every: Select the frequency (Day, Week, Month, Year).​
    • On: Specify the days of the week or months, depending on the chosen frequency.​
    • On the: For monthly or yearly frequencies, define positions like First, Second, Third, Fourth, or Last, and select the corresponding day.​
  3. Set the End Condition:
    • Never: The event repeats indefinitely.​
    • After: Specify a number of occurrences.​
    • On Date: Set a specific end date.​
  4. Generate the RRULE: As you configure the settings, the generator dynamically creates the RRULE code.​
  5. Copy and Implement: Once satisfied with the configuration, copy the result from the RRULE generator and add it to your calendar event as needed.​

Our handy RRULE generation tool eliminates the need for manual coding, reducing errors and streamlining the scheduling process.​

Use AddEvent to Avoid Writing RRULES

Okay, so you’ve followed along and you’re still not sold – we get it – you can sign up for a free AddEvent account where you can create recurring events without needing to write an RRULE for the rest of your days. The best part? Not only do you never need to write a recurring rule again, your events will also have a landing page and add to calendar buttons automatically created, so you can market your events faster than ever. 

Difference Between Recurring Events and Event Series in AddEvent

If you’re creating an event in AddEvent, you might have noticed an option for “event series” in addition to a “recurring event.” 

While both recurring events and event series deal with repeated events, they differ in their structure and management:​

  • Recurring Events: In AddEvent,”recurring events” allow users to create an event that repeats on an ongoing schedule without having to write the RRULE (recurring rule) themselves. The key thing to note is that recurring events are the same event displayed on multiple days, and as such, cannot be edited for individual instances.
  • Event Series: In AddEvent, an “event series” will bulk create individual events with the same properties based on the cadence you set. Event series allow AddEvent users to make changes to individual events that occur on a regular schedule, unlike recurring events which must all have the same detailed information.

When to use an Event Series Instead of a Recurring Event

Not sure when to use a recurring rule vs an event series? We get it, it’s confusing, so let’s use a common example – regularly scheduled webinars. 

If you have a monthly webinar series for your clients to attend and it is always on the 4th Thursday of the month, in November, you would see the monthly webinar event fall on Thanksgiving

If you set this event up as a recurring event, you wouldn’t be able to edit or remove the event that falls on Thanksgiving as you can’t edit individual dates of a recurring event and would therefore want to set it up as an event series that creates x amount of webinar events at a time. 

In essence, the recurring rule is best for events that are always the same and event series is perfect for events that are repeatable but sometimes have different event details or need to be adjusted.

What is a recurring rule?

A recurring rule (RRULE) defines the pattern by which an event repeats over time in a calendar system, specifying details like frequency, interval, specific days, and end conditions.​

How do I create a recurring rule?

You can create a recurring rule manually by writing an RRULE following the iCalendar standard format, or use a tool like AddEvent’s Recurring Rule Generator to simplify the process through an intuitive interface.​

What’s the difference between a recurring rule and an event series?

A recurring rule is the defined pattern dictating how an event repeats, while an event series is a way to bulk create events that have a regular cadence..​

By leveraging AddEvent’s Recurring Rule Generator, users can efficiently manage complex recurring events, ensuring accuracy and saving time in their scheduling endeavors.
