For a recurring project checkpoint—such as a weekly review, monthly release, or quarterly planning meeting—create a repeating event in Calendar on your Mac, set an end point if the series is temporary, and keep its title and notes clear. Use a separate project calendar when you want these events to be easy to spot or hide. Calendar repeats events on a schedule; if each milestone date changes with project progress, create individual events instead of a fixed recurrence.

Decide whether the milestone really repeats

A repeat is useful when the event follows a stable cadence: for example, a review every other Friday or a release check-in on the first Monday of each month. Before creating a series, decide the first date, cadence, time, and whether it should end after a known number of cycles or date. Apple Calendar supports standard repeat choices and custom daily, weekly, monthly, and yearly patterns, as well as an end condition. Set up or delete a repeating event in Calendar on Mac

A project milestone that moves whenever a prior task finishes is different. A repeating event schedules later dates by pattern; it does not represent a dependency that automatically shifts when work slips. For changeable dates, add each milestone separately and update it as the plan changes. This distinction is a practical consequence of Calendar’s documented repeat controls, which ask for a frequency or pattern and when repetition stops.

Create a calendar for the project

In Calendar, choose File > New Calendar, give it a project-specific name, and press Return. If the calendar list is hidden, choose View > Show Calendar List. Separate calendars have their own colors, and you can show or hide them in the calendar list—helpful when you want project milestones visually distinct from other commitments. Apple notes that a calendar created this way may belong to the On My Mac section; if you need a calendar associated with a particular account, create it through that account’s provider when necessary.

Create and configure the recurring event

Create the first occurrence on the project calendar. In Day or Week view, double-click the date or time (or drag across a time range); in Month view, double-click the day. Enter a concise name that includes the milestone and project, such as “Project Orion — sprint review.” Open the event details to add the relevant start and end time, then click the event’s time to access repeat settings.

Choose a repeat option from the Repeat menu. For a cadence not listed, choose Custom and select a frequency. For example, to schedule a review every two weeks, choose a weekly pattern and enter an interval of two weeks, selecting the weekday. For a monthly milestone tied to a calendar date or a pattern such as a weekday occurrence, use the monthly custom settings that match your plan. Set End Repeat to the date or condition that reflects the project’s known duration; if the work has no defined end date, leave the series ongoing and review it as the project changes. The available custom patterns depend on frequency, so check the resulting dates in Calendar before relying on the series. Set up or delete a repeating event in Calendar on Mac

Add a useful alert if you need advance notice. In event details, click the event’s time, then use the Alert menu. Put a short agenda, preparation checklist, or link in the event notes so each occurrence carries the same context. Calendar supports alerts and event notes, URLs, and attachments.

Keep changes and exceptions manageable

When the schedule changes, edit the repeating event’s settings and confirm the change. If only one occurrence is canceled, delete that occurrence alone; if the series is over, delete all occurrences. Calendar also offers a choice to delete selected occurrences and all future events. These options matter: deleting the whole series for a single conflict can remove future checkpoints, while leaving an obsolete series active can clutter the project calendar.

For a one-time date shift, move or edit the affected occurrence and pay attention to Calendar’s prompt about how broadly the change applies. If future milestones have individually negotiated dates, consider replacing the recurrence with separate events rather than maintaining a pattern that no longer describes the project.

Use reminders for the work between milestones

Calendar events are suited to scheduled checkpoints; action items such as “prepare demo” or “send release notes” fit better as Reminders. You can schedule reminders and show them in Calendar by enabling Scheduled Reminders in the calendar list. A repeating reminder advances to its next occurrence when the previous one is completed, which differs from a repeating Calendar event that lays out scheduled occurrences. Reminder availability in Calendar depends on using updated iCloud reminders; some features may not be available with other accounts. Create reminders in Calendar on Mac

A simple rule keeps the project calendar useful: use recurring events for stable meetings or review cycles, single events for dates that change with project progress, and reminders for tasks that need completion. Review the series when the cadence or project end date changes so the calendar continues to reflect the plan.
