# Date Overrides or Set Unavailable

**Date overrides** let you change your hours for a specific day — or block it entirely — without changing your regular weekly routine. Pick any date you're normally available and set custom hours, or **mark yourself unavailable**. Taking Thursday afternoon off? Add an override just for that day.

| When to use this

* **Taking a day off** — a holiday or personal day.
* **A one-time commitment** — you're busy for a couple of hours on a specific day.
* **Special hours** — you want to work reduced hours on a holiday.

| How to add an override

1. Open **Availability** and click the schedule you want to adjust.
2. Scroll to the **Date Overrides** section at the bottom.

3. Click **+ Add an override** and pick the date on the calendar.
4. Set what happens that day:
* **Busy all day:** toggle on **Mark unavailable (all day)**.
* **Different hours:** choose the hours you're free for that day only.

5. Click **Save Overrides**, then click **Save** at the top of the page.

| How it works

* **Overrides take priority.** If your weekly schedule says you're free but an override says busy, Cal ID shows you as **busy**.
* **They're temporary.** Once the date passes, your calendar returns to its normal weekly schedule automatically.
