# Set Holiday & Closure Dates
> Override a facility's normal hours on specific dates — close for a holiday, or open a normally-closed day.
**Where to find it:** `Master Data → Facilities → [your facility] → Settings → Holiday & Closure Dates`
Holiday and closure dates are rules pinned to specific calendar dates. On a date that has an entry, that entry **replaces** your normal weekly operating hours for the whole facility — every customer, both pickup and dropoff, and all docks.
Despite the name, an entry doesn't have to close anything. Each entry is a toggle between **Closed all day** and **Custom hours**, and a custom-hours entry can narrow your normal hours, widen them, or open a day you're normally closed — for example, opening a Saturday for a one-off inbound push. Think of the section as "override this date's hours."
## What an Entry Contains
Every entry is a date plus one of two behaviors:
* **Closed all day**: the facility takes no appointments on that date.
* **Custom hours**: the facility is open only during the time windows you set. The default window is 9:00 AM to 5:00 PM.
You can add more than one custom window to a single date to model a split day — for example, 6:00 AM to 11:00 AM and 1:00 PM to 6:00 PM for a lunch shutdown.
## Three Ways to Pick a Date
### US Holiday
Pick a holiday by name, such as **Thanksgiving Day**. The menu is searchable and multi-select, so it stays open while you add several at once. A holiday can only be added once.
Holidays always recur. Owlery re-resolves the actual date each year, so a moving holiday like Thanksgiving (the fourth Thursday of November) stays correct without you touching it.
Only US **public** holidays appear in the list. Observances like Mother's Day or Halloween aren't included, and neither are weekend "substitute day" entries. For a company-specific closure — an inventory day, a plant shutdown — use **Pick a specific date** instead.
### Specific Date, One Time
A single calendar date that applies once and never repeats.
### Specific Date, Every Year
Turn on the **Every year** switch to make the same month and day recur annually — useful for a fixed-date closure like a company anniversary.
An **Every year** entry on February 29 only applies in leap years.
## Precedence When Rules Collide
More than one rule can land on the same date. The most specific one wins, so you can carve out one exceptional year without deleting a standing rule.
| Priority | Entry type | Example |
| ----------- | --------------------------- | ------------------------------------------- |
| 1 — highest | One-time specific date | Open 8:00 AM–12:00 PM on Dec 24, 2026 only |
| 2 | "Every year" recurring date | Closed every Dec 24 |
| 3 — lowest | US holiday | Closed on Christmas Eve as a listed holiday |
## Combinations You Can't Save
Two rules on the same date will be rejected when they can't both be true:
* **Closed all day plus anything else** on the same date is a conflict.
* **Overlapping custom windows** on the same date are a conflict.
Multiple custom windows that don't overlap are fine — that's how you build a split day.
## How Blocked Dates Affect Booking
* **In the booking calendar**: blocked dates and times are greyed out, so no one can select them.
* **On submit**: if someone had the page open before you saved the rule, the booking is still rejected, with a message naming the facility, the date, and the reason.
* **A full-day closure is absolute**: it blocks the date for everyone, even a customer who has a reserved slot under a customer-specific schedule. Only owners and Owlery admins are exempt.
* **A partial window only narrows what was already open**: time that was never in your normal operating hours stays closed, and isn't reported as newly blocked.
## Timezone and List Behavior
* **Everything is facility-local**: dates and times are shown and resolved in the facility's own timezone, even when you're viewing from another zone.
* **Past one-time dates leave the list**: they disappear once they've passed, but they're still kept in the saved data.
* **A holiday name that no longer exists**: if a holiday leaves the catalog, it stops blocking and the date opens back up. The settings page shows a warning asking you to remove the entry.
## What Bookers See
Owners see these rules on the dock calendar as non-clickable **Blocked** overlays across the affected date or hours.
Carriers and other bookers see neither the overlay nor the reason — the date or timeslot simply isn't available to pick. If you want a carrier to know *why* the dock is closed, tell them directly.
## Who Can Change This
Only the facility's owning organization can add, edit, or remove holiday and closure dates. Everyone else sees the section read-only, and only once entries already exist — enough to explain times they can't book, but not to change them.
## Related Settings
Your normal weekly operating hours, appointment length, and capacity — the rules these dates override.
Hold a single dock for a few hours instead of changing the whole facility's hours.
