Mozilla Sunbird

Mozilla Sunbird is a cool cross-platform calendar made by Mozilla. It supports tons of extensions and add-ons, making it super flexible for your needs.

Easy to Use Layout

This app has a clean and user-friendly layout. You can keep multiple calendars, flip through the months, and easily view your day, week, or month. It’s all about making scheduling simple!

Create Events with Ease

With Mozilla Sunbird, you can easily create new events or tasks. Just fill in the title and location, choose a category (like anniversaries or holidays), add a description, pick start and end dates, and set reminders. It’s that simple!

Invite Others & Manage Tasks

You can also invite attendees to your events! Plus, you have options to insert URLs, set priority levels, and even undo or redo your actions. Need to cut, copy or paste? No problem at all!

Importing & Exporting Made Easy

The app lets you import information from ICS or CSV files and export it back out in those formats too. Searching for events is straightforward as well! You can view completed tasks and apply add-ons whenever you want.

Customize Your Settings

There are lots of configuration settings available too! Change date text formats, snooze lengths for reminders, sound notifications (you can even upload an audio file!), and select the closest city in your time zone.

Your Scheduling Companion

All in all, Mozilla Sunbird is an awesome tool for keeping track of your schedule without any fuss. If you're looking for something portable that skips installation steps, check out the portable version here. Just a heads up though—the project has been discontinued.
