# Blocked days and calendar colors
## Visual indicators on the calendar
The Calendar uses color to communicate availability at a glance. When a day is affected by a booking exception, it is visually marked so you can immediately see which days have restricted availability.
### Fully blocked days — Red
A day marked in **red** is **completely blocked**. No appointments can be booked at any time on that day.
A red indicator means that an exception with **Block entire day** enabled is active for that date. The entire day — from the first business hour to the last — is unavailable for scheduling.
### Partially blocked days — Yellow
A day marked in **yellow** has a **partial block**. Some hours are blocked by an exception, but other hours remain available for appointments.
A yellow indicator means that an exception with specific **override hours** is active for that date. For example, if the exception blocks 9:00 AM to 11:00 AM, the rest of the day's business hours remain open.
### Color behavior across views
The red and yellow indicators appear in all three calendar views:
| View | How blocked days appear |
|------|------------------------|
| **Month** | The date cell is highlighted in red or yellow |
| **Week** | The column for that day shows the color indicator |
| **Day** | The blocked time ranges are highlighted within the timeline |
This consistent color behavior makes it easy to spot availability restrictions regardless of which view you are using.
## The day drawer
When you click on a day that is marked in red or yellow, a **right-side panel** (drawer) opens with detailed information and controls for that day.
### What the drawer shows
The drawer displays:
- **The selected date** — The specific date you clicked on
- **Regular business hours** — Your configured business hours for that day of the week
- **Appointment details** — Any appointments already booked on that day, if they exist
- **Exception details** — Information about the exception affecting that day
- **Management controls** — Actions you can take to modify the block
- **Open day view** — A button to open the full day view for more space and detail
Note
The drawer is a quick-access tool for reviewing and adjusting blocks without leaving the calendar. For comprehensive exception management including filtering and bulk actions, use the Exceptions page.
## Drawer behavior for fully blocked days (red)
When you click on a **red** (fully blocked) day, the drawer opens with these available actions:
### Remove the block
You can remove the exception entirely, making the day available for appointments again. This is useful when a planned closure is cancelled and you want to reopen the day.
### Edit to partial block
Instead of removing the block completely, you can **convert it to a partial-day block**. This changes the exception from a full-day block to specific blocked hours, opening up the rest of the day for appointments.
For example, if an entire day was blocked for a team event that was shortened to the morning only, you could edit the block to cover just 9:00 AM – 12:00 PM, making the afternoon available.
## Drawer behavior for partially blocked days (yellow)
When you click on a **yellow** (partially blocked) day, the drawer opens with different actions:
### Block the full day
If the partial block is not enough and you need to close the entire day, you can upgrade the exception to a full-day block. This converts the yellow partial block into a red full-day block.
### Edit the override hours
You can modify the specific hours that are blocked. If the original exception blocked 9:00 AM – 11:00 AM and you need to extend it to 9:00 AM – 1:00 PM, you can adjust the time range directly from the drawer.
### View effective hours
The drawer shows the **effective hours** for the partially blocked day. Effective hours are the remaining available hours after the blocked time is subtracted from the regular business hours.
For example:
| Component | Hours |
|-----------|-------|
| Regular business hours | 9:00 AM – 5:00 PM |
| Exception blocks | 9:00 AM – 11:00 AM |
| **Effective hours** | **11:00 AM – 5:00 PM** |
This makes it clear at a glance exactly when appointments can still be booked.
### View exception details
The drawer also shows the details of the exception affecting that day:
- The exception type (single day, date range, or recurring)
- The reason, if one was provided
- The time range being blocked
Tip
The distinction between red and yellow days is important for team communication. Red means "completely closed" while yellow means "partially available." If you manage a team, make sure everyone understands that yellow days still have bookable slots.
