# Set up a lesson that repeats every week

> A repeat creates a real, separate booking for every date, so each one can be ramped, reviewed and invoiced on its own. Every repeat has an end, and if one date conflicts none of them are booked.

Source: https://www.aerscheduler.com/docs/scheduling/set-up-a-repeating-booking
Section: Scheduling and dispatch. For: Owners, Admins, Dispatchers, Instructors, Students, Renters.

Fill the booking in first, including the start and end times, then open **Repeat** and
pick a preset. A repeat creates a real, separate booking for every date, so each one is
ramped, reviewed and invoiced on its own. If any one date clashes, none of them are
booked.

**Who can do this:** Owners, Admins, Dispatchers, Instructors, Students, Renters

## Fill in the first booking first

The Repeat control builds its options from the date and time you have already chosen, so
it has nothing to offer until they are set. Pick the type, the resource, the people, the
date, the start and the end, and only then open Repeat.

## Pick a repeat preset

Open the **Repeat** dropdown, above Notes. The presets are written from your chosen date,
so booking Monday 9 March gives you a list like this:

- Does not repeat
- Daily
- Weekly on Monday
- Every 2 weeks on Monday
- Monthly on the second Monday
- Monthly on day 9
- Annually on March 9
- Every weekday (Monday to Friday)
- Custom…

One extra entry, **Monthly on the last Monday**, appears only when your date really is the
last of that weekday in the month.

## Build a custom repeat

Pick **Custom** at the bottom of the list to open the custom repeat dialog. It lets you
set:

- The interval, for example every 3 weeks. The interval is capped at 12.
- Several days a week at once, for a Tuesday and Thursday lesson.
- Which sense of monthly you mean: the same date each month, or the same weekday of the month.
- Where the series ends: after a number of bookings, or on a date.

> **Note:** A weekly rule has to keep at least one weekday selected. The picker will not let you clear
> the last one.

## Read the summary line before you book

Under the control, AerScheduler writes back what it is about to do in plain language, with
the number of bookings it will create. Something like `Repeats every week on Monday` and a
count of 12.

Read it. It is the only place the count appears before the bookings exist.

Press **Book reservation** and the toast reads `Repeating booking created`.

## How many bookings you get

There is no "repeats forever". Every occurrence holds a real aircraft for a real hour, so
a repeat that never ended would block the fleet indefinitely. These limits apply:

| Limit                                     | Value                                                            |
| ----------------------------------------- | ---------------------------------------------------------------- |
| Bookings created at once                  | 200, or your school's **max upcoming bookings** if that is lower |
| How far out a daily or weekly repeat runs | About 400 days                                                   |
| How far out a monthly repeat runs         | About 3 years                                                    |
| How far out a yearly repeat runs          | About 10 years                                                   |

If the school has set a max upcoming bookings rule under Booking preferences, a repeat that
would push the member over that cap is refused. Existing upcoming bookings count toward the
same limit, so a member with 5 already held and a school cap of 20 can only create a series
of 15 more. The Repeat control will not offer an “After N” count above the school limit.

> **Careful:** A monthly repeat on a day past the 28th **skips** the months that do not have that day. A
> booking on the 31st does not move to the end of February, it simply does not happen that
> month.

## If one of the dates conflicts

The whole series is all or nothing. If one of twelve Tuesdays clashes with something
already on the board, nothing at all is booked and the error names up to five of the
clashing dates, ending with `Nothing was booked.`

Clear the conflict, shorten the series, or move the time, then book again.

## Changing or cancelling a repeat later

Two things to know before you commit to a cadence.

**Editing one booking edits only that booking.** Open it, press Edit reservation in the
panel's … menu, change what you need. The rest of the series is untouched.

**The repeat rule itself cannot be changed.** The Repeat control is offered when you create
a booking and not when you edit one. To move a lesson from Mondays to Wednesdays, cancel
the series and book it again.

Cancelling asks what you mean: this booking only, this and all later bookings, or all
bookings in the series. Bookings that have already started are never cancelled, whichever
you pick. See [Cancel a booking and record why](https://www.aerscheduler.com/docs/scheduling/cancel-a-reservation).

> **Note:** A repeat sends one notification for the whole series rather than one per booking. Anyone
> with Google Calendar connected does get an event for every occurrence.
