Getting Things Done (GTD) with Google Calendar

David Allen's Getting Things Done (GTD) is one of the most influential productivity methodologies ever created. At its core, GTD is about getting tasks out of your head and into a trusted system so you can focus on doing, not remembering.

Google Calendar can be that trusted system. Here's how.

GTD in 5 Steps

1. Capture

Get everything out of your head. Every task, idea, commitment, and reminder goes into an "inbox" — a single collection point.

With Google Calendar: Use a quick-capture method to dump tasks. With Skedio, type naturally: "Call accountant 30min due Wednesday #finance" and it's captured instantly.

2. Clarify

For each item in your inbox, decide: Is it actionable? If yes, what's the next action? If no, trash it, file it for reference, or add it to a "someday" list.

The two-minute rule: If an action takes less than two minutes, do it immediately. Don't schedule it — just do it.

3. Organize

Put actionable items where they belong:

• Calendar: Tasks that must happen at a specific time or on a specific day
• Next actions: Tasks you can do whenever you have time
• Waiting for: Tasks delegated to others
• Projects: Multi-step outcomes you're working toward

With Google Calendar: Your calendar becomes the hub. Time-specific tasks go directly on the calendar. For "next actions," use a simple list or let a tool like Skedio schedule them into open slots.

4. Reflect

Review your system regularly:

• Daily review: Check your calendar and task list each morning
• Weekly review: Every week, review all projects, next actions, and waiting-for items

The weekly review is the backbone of GTD. Without it, the system breaks down.

5. Engage

With a trusted system in place, you can focus on doing the work in front of you. Your calendar tells you what's next. Your brain is free to focus on execution, not remembering.

Why Google Calendar Works for GTD

It's Already Your Schedule

Most people already check Google Calendar multiple times a day. Adding tasks there means they're always visible.

Time-Blocking Aligns with GTD

GTD emphasizes context — doing the right task at the right time. Time-blocking tasks in your calendar ensures they happen when conditions are right.

Universal Access

Google Calendar syncs across every device. Your GTD system is always with you.

A Simple GTD Setup

You don't need a complex tool. Here's a minimal GTD setup with Google Calendar:

• Capture: Quick-add tasks to Skedio (or your preferred capture tool)
• Process: Review new tasks daily — set durations and deadlines
• Calendar: Tasks with durations automatically appear in Google Calendar
• Weekly review: Spend 15 minutes each week reviewing your calendar and task list
• Do: Follow your calendar. When a block starts, do the work.

Common GTD Mistakes

Over-Complicating the System

GTD is a methodology, not a tool specification. Don't get caught up building the perfect system. A basic capture tool + Google Calendar covers 90% of what you need.

Skipping the Weekly Review

This is the most common failure point. Without regular reviews, items slip through the cracks and you lose trust in the system.

Too Many Categories

Start with: Calendar, Next Actions, and Waiting For. Add more only when you genuinely need them.

Getting Started

• Choose a fast capture tool (Skedio, a notes app, or even pen and paper)
• Do a full brain dump — get everything out of your head
• Process each item: schedule it, do it, delegate it, or delete it
• Set a recurring 15-minute weekly review on your Google Calendar
• Trust the system and focus on doing

GTD works because it's simple in principle. Keep it simple in practice, too.
