Calendar Blocking (Time Blocking)

Overview

Calendar Blocking (Time Blocking) involves scheduling specific blocks of time on your calendar for particular tasks or types of work, providing structure and protecting focus time from meeting encroachment.

Core Practice

Treat appointments with yourself (for focused work) with the same respect as appointments with others (meetings).

Implementation Methods

Task-Based Blocking

• Specific task assigned to each block
• "Write quarterly report 9-11am"
• Clear, concrete objectives
• Measurable completion

Theme-Based Blocking

• Type of work, not specific task
• "Marketing work 2-4pm"
• "Email and admin 4-5pm"
• Flexible within theme

Time-Based Blocking

• Deep work blocks
• Shallow work blocks
• Meeting blocks
• Break blocks

Types of Blocks

Focus Blocks

• Deep work time
• 90-120 minutes typically
• No meetings, no interruptions
• Most important work

Meeting Blocks

• Consolidate meetings
• Prevent calendar fragmentation
• Easier for others to schedule
• Preserves long focus blocks

Admin Blocks

• Email processing
• Routine tasks
• Quick communications
• Housekeeping work

Break Blocks

• Lunch
• Exercise
• Mental recovery

Buffer Blocks

• Transition time
• Preparation for meetings
• Overflow capacity
• Flexibility

Best Practices

Realistic Scheduling:

• Don't overpack
• Include buffers
• Account for energy levels
• Leave emergency capacity (20-30%)

Color Coding:

• Visual clarity
• Quick pattern recognition
• Different types distinct
• Aesthetic appeal

Protect Blocks:

• Decline meeting invites during focus blocks
• Communicate boundaries
• Reschedule conflicts
• Say no to interruptions

Review and Adjust:

• What worked/didn't
• Refine estimates
• Adjust block sizes
• Improve over time
