The Ultimate Guide to Using Google Calendar with Centauri

Google Calendar is powerful. Centauri makes it intelligent. Learn how to connect them and unlock AI-powered scheduling that adapts to your life.

If you're a student, Google Calendar is probably already part of your life. Class schedules, assignment deadlines, club meetings, study groups—it's all in there. But here's the problem: Google Calendar is a storage tool, not a thinking tool. It holds your events but doesn't help you optimize them.

That's where Centauri comes in. By connecting Google Calendar to Centauri, you get an AI layer that analyzes your schedule, suggests optimal time blocks, protects your focus time, and adjusts automatically when things change.

This guide covers everything: initial setup, sync configuration, best practices, and advanced strategies for building the perfect student calendar system.

Why Connect Google Calendar to Centauri?

🔄 Two-Way Sync

Events flow both directions. Add a deadline in Centauri, see it in Google Calendar. Schedule a meeting in Google, it appears in Centauri.

🧠 AI Analysis

Centauri reads your calendar to understand your commitments, then suggests when to schedule study sessions, breaks, and tasks.

⏰ Smart Scheduling

Instead of manually finding free time, tell Centauri what you need to do and it finds the optimal slot based on your patterns.

🛡️ Focus Protection

Mark certain blocks as deep work time. Centauri won't suggest tasks or meetings during these protected windows.

Setting Up the Integration

Connecting Google Calendar to Centauri takes about 2 minutes. Here's the step-by-step process:

1 Access Integrations

In Centauri, navigate to Settings → Integrations → Google Calendar. You'll see a "Connect Google Account" button.

2 Authorize Access

Click the button and sign in with your Google account. You'll see a permissions screen asking Centauri to view and edit your calendar. This is required for two-way sync—Centauri needs edit access to add scheduled study blocks and tasks.

3 Select Calendars

After authorization, you'll see a list of your Google calendars. Select which ones Centauri should read. Typically you want:

  • Primary calendar: Your main personal calendar
  • Class schedule: If your university syncs courses to Google Calendar
  • Shared calendars: Study groups, club schedules, etc.

You can also choose one calendar where Centauri will write events (usually your primary calendar).

4 Initial Sync

Centauri will pull your upcoming events and begin analyzing your schedule. This usually takes 30-60 seconds. Once complete, you'll see your Google Calendar events reflected in Centauri's calendar view.

Pro Tip: If you have a separate "Tasks" or "Deadlines" calendar in Google, you can set Centauri to only write to that calendar, keeping your main calendar clean.

Understanding How Sync Works

What Gets Synced

What Centauri Creates

When Centauri schedules something for you, it creates a Google Calendar event with:

Sync Frequency

Changes sync in near real-time:

Note on Recurring Events: Centauri reads recurring events from Google Calendar but creates them as individual instances when scheduling. This gives you flexibility to adjust specific occurrences without affecting the entire series.

Best Practices for Student Calendars

1. Use Separate Calendars for Different Life Areas

In Google Calendar, create separate calendars for:

Color-code each calendar differently. This makes it easy to see at a glance what type of commitment fills each slot.

2. Block Your Class Schedule First

Before the semester starts, add all your classes as recurring events. Include:

Centauri uses these fixed blocks to schedule around, so accuracy here prevents conflicts.

3. Mark Your Non-Negotiables

Block time for things that shouldn't be scheduled over:

In Centauri, you can mark these as "protected" so AI scheduling won't suggest tasks during these times.

4. Add Deadlines Immediately

When a professor announces a deadline, add it to your calendar immediately—before you leave the classroom if possible. Include:

Centauri can read these deadlines and automatically suggest when to start working on each assignment.

Advanced Strategies

Time Blocking with AI Assistance

Traditional time blocking requires you to decide when to do each task. With Centauri, you can:

  1. Add your tasks with time estimates
  2. Set their deadlines
  3. Let Centauri suggest optimal blocks
  4. Approve, adjust, or regenerate the schedule

The AI considers your energy patterns (if you tell it you're a morning person), class schedule, existing commitments, and task dependencies.

Example: Essay Planning

You have an essay due Friday at 5 PM. You tell Centauri:

  • Task: "Write History Essay"
  • Estimated time: 6 hours
  • Deadline: Friday 5 PM
  • Preference: "No writing after 8 PM"

Centauri looks at your week, sees you have gaps Tuesday morning and Thursday afternoon, and suggests two 3-hour blocks. It creates Google Calendar events for both, and you get reminders before each.

Buffer Time Automation

Centauri can automatically add buffer time around events. Enable this in settings to:

Weekly Review Integration

Each Sunday, Centauri can generate a weekly planning summary showing:

This integrates with your Google Calendar view for a complete picture of the week ahead.

Troubleshooting Common Issues

Events Not Syncing

Duplicate Events

If you see duplicates, it's usually because:

Solution: Delete the duplicate in one location. The sync will remove it from the other.

Wrong Calendar Selected

If Centauri is writing events to the wrong calendar, go to Settings → Integrations → Google Calendar and change the "Write events to" calendar selection.

Timezone Issues

If events appear at wrong times:

Privacy and Data

Connecting your calendar means sharing data. Here's what to know:

Getting the Most from the Integration

The Google Calendar + Centauri combination works best when you:

  1. Keep Google Calendar as your source of truth for fixed events (classes, meetings, appointments)
  2. Let Centauri handle flexible scheduling (study sessions, tasks, assignments)
  3. Review AI suggestions before accepting—you know your energy and preferences better than any algorithm
  4. Maintain your calendar—delete cancelled events, update changed times, keep it current
  5. Trust the protected time—if you block personal time, actually take it
"The calendar isn't just for storing events. It's for designing your days intentionally. Let AI help with the logistics so you can focus on living."
