Thunderbird Lightning

One of the best free Linux calendar programs is Thunderbird. This tool is also used for emails and provides calendar functionality. You can get Thunderbird from the add-on and also directly use it from the app. You can access the task, email, and calendar tabs separately. It is simple to use for appointment scheduling, management, and team communication.

The Thunderbird Lightning gives you a calendar tab where you can view a complete summary of all the events in your schedule. The next events are also displayed. With time filters and built-in categories for client calls, birthdays, special events, etc., you can conveniently search for your events. It may be downloaded for Windows and is the ideal option for Linux users. Organizing your schedule and life’s important events in a calendar that’s fully integrated with your Thunderbird email is truly convenient. You can manage multiple calendars, create your daily to-do list, invite friends to events, and subscribe to public calendars.
