How to Block Websites at Certain Times with Chrome Extensions

Learn how to set up scheduled website blocking that automatically activates during work hours, study sessions, or any custom time period you define.

Why Time-Based Blocking Works Better

Complete website blocking often backfires. Time-based blocking creates a sustainable approach: distractions are off-limits during focus time but available during breaks.

Setting Up Scheduled Blocking

Step 1: Choose Your Extension

• Deep Work Zone (Recommended): Most flexible scheduling

• StayFocusd: "Active Hours" settings

• Cold Turkey: Locked schedule blocks

Step 2: Define Your Schedule

• Monday-Friday, 1 PM - 5 PM: Block entertainment

• Weekends: Light or no blocking

Student Schedule

• Weekdays, 9 AM - 12 PM: Morning study block

• Weekdays, 2 PM - 6 PM: Afternoon study

• Weekdays, 7 PM - 9 PM: Evening review

Step 3: Configure in Deep Work Zone

1. Click the Deep Work Zone icon

2. Navigate to Settings → Schedules

3. Click "Add Schedule"

4. Set days and times

5. Select block list

6. Enable "Auto-start"
