 - **Clear Feedback**: Users see exactly which items need to be completed first
 - **Error Prevention**: System prevents circular dependencies automatically
 
+## Item Date Constraints
+
+The application supports date constraints, allowing you to set time windows when
+items can be completed.
+
+### How Date Constraints Work
+
+- **Not Before**: Set the earliest time an item can be completed
+- **Not After**: Set the latest time an item can be completed
+- **Validation**: Items cannot be completed outside their allowed time window
+- **Visual Indicators**: Items show date constraint status with color-coded
+  indicators
+- **Real-time Updates**: Constraint status updates in real-time
+
+### Managing Date Constraints
+
+1. **Set Constraints**: Click the clock icon (🕐) on any item to open the date
+   constraint manager
+2. **Configure Times**: Set "not before" and/or "not after" times
+3. **Visual Feedback**: Items show constraint status:
+   - 🟢 Green: Time constraints met (shows "Ready")
+   - 🔴 Red: Time constraints not met (shows "Time locked")
+4. **Completion Prevention**: Items cannot be checked off outside their time
+   window
+
+### Date Constraint Features
+
+- **Flexible Scheduling**: Set any combination of start and end times
+- **ISO 8601 Format**: Uses standard datetime format for precision
+- **Real-time Validation**: Constraint status updates immediately
+- **Clear Feedback**: Users see exactly when items can be completed
+- **Error Prevention**: System prevents completion outside allowed times
+
+### Example Use Cases
+
+- **Meeting Preparation**: Set items to be completed before a meeting starts
+- **Deadline Management**: Set items to be completed by a specific deadline
+- **Time-sensitive Tasks**: Ensure tasks are completed within business hours
+- **Sequential Workflows**: Use in combination with dependencies for complex
+  workflows
