Whenami

A powerful Google Calendar tool that merges multiple calendars to find your true availability across work and personal schedules.

Description

whenami is a command-line tool designed for people who juggle multiple calendars (work, personal, side projects, etc.). Its key strength is merging multiple Google Calendars to show your real availability by combining busy periods from all sources.

Key Features:

• 🗓️ Multi-calendar support: Connect work calendars, personal Gmail calendars, shared calendars
• 🔀 Smart merging: Automatically merges busy periods from all calendars to show true availability
• ⏰ Flexible time filtering: Personal hours (awake time), work hours, or 24/7 view
• 🎨 Color-coded output: Green for free slots, red for busy periods
• 🌍 Advanced timezone handling: Automatically detects each calendar's timezone, merges events correctly across timezones, and converts output to any timezone
• 📅 Multiple date ranges: Today, tomorrow, next week, or custom date ranges with flexible date formats

Perfect for professionals who need to see availability across multiple calendars without manually checking each one.

Timezone Support

whenami intelligently handles complex timezone scenarios:

Multi-Timezone Calendar Merging

• Auto-detection: Automatically detects each calendar's native timezone (e.g., work calendar in EST, personal in PST)
• Smart merging: Converts all events to a common timezone before merging busy periods
• Accurate overlap detection: Ensures proper conflict detection across timezone boundaries

Flexible Output Conversion

# View in your local timezone (default)
whenami --today

# Convert to a specific timezone for travel/meetings
whenami --today --convert-tz Europe/London
whenami --next-week --convert-tz Asia/Tokyo

# List all available timezones
whenami --list-tz

Real-World Example

If you have:

• Work calendar in America/New_York (EST/EDT)
• Personal calendar in America/Los_Angeles (PST/PDT)
• University calendar in Europe/London (GMT/BST)

whenami will automatically handle the conversions and show your true availability across all timezones, optionally converting the final output to any timezone you specify.

Configuration

The tool will automatically create a ~/.config/whenami/ directory for storing configuration files. You can place your configuration files there for system-wide access, or use the current directory for project-specific configurations.

1. Copy the example config file:

cp config.json.example ~/.config/whenami/config.json

2. Edit config.json with your calendar settings:

{
    "calendars": [
        {
            "id": "[e-mail]",
            "name": "Work Calendar"
        },
        {
            "id": "[e-mail]",
            "name": "Personal Calendar"
        },
        {
            "id": "[e-mail]",
            "name": "Shared Project Calendar"
        },
        {
            "id": "[e-mail]",
            "name": "University Calendar"
        }
    ],
    "work_hours": {
        "start": "09:00",
        "end": "17:00"
    },
    "personal_hours": {
        "start": "08:00",
        "end": "22:00"
    },
    "minimum_slot_duration": 30,
    "default_timezone": "Europe/Dublin"
}

Configuration Options

• calendars: Array of calendar objects with id and name fields
• work_hours: Define work hours (start/end times in 24-hour format)
• personal_hours: Define personal hours (start/end times in 24-hour format)
• minimum_slot_duration: Minimum duration in minutes for free slots to be displayed
• default_timezone: Default timezone for date calculations (e.g., "Europe/Dublin", "America/New_York", "UTC")

📝 Note: Add as many calendars as needed - the tool will merge all busy periods to show your true availability across all calendars. This is especially useful if you have separate work, personal, and project calendars that you need to coordinate.

The default_timezone setting controls the timezone used for date calculations (e.g., "today", "tomorrow"). If not specified, the tool will try to use your system's timezone, falling back to UTC.

Authentication

The tool requires Google Calendar API authentication:

1. Go to Google Cloud Console
2. Create a new project or select an existing one
3. Enable the Google Calendar API
4. Create OAuth 2.0 credentials (Desktop application)
5. Download the credentials and save as credentials.json in one of these locations:
   • ~/.config/whenami/credentials.json (recommended for system-wide access)
   • ./credentials.json (current directory, for project-specific setup)

The first time you run the tool, it will open a browser window for authentication. The authentication token will be saved in ~/.config/whenami/token.json for future use.

Development

This project uses GitHub Actions for CI/CD:

• CI Pipeline: Runs tests on Python 3.9-3.12, generates coverage reports, and validates builds
• PyPI Publishing: Automated publishing to PyPI on releases using trusted publishing
