Add a Powerful Calendar to Thunderbird with Lightning

While there aren’t a lot of full-feature email and calendar alternatives to Microsoft Outlook, Mozilla’s Thunderbird comes close, and it’s free. The thing is, Thunderbird doesn’t have a calendar by default.  Lightning is a free add-on that brings in a full-feature calendar and task system, similar to what you would find in Outlook. Lightning can pull down and sync with Google calendar, Exchange, and other calendars. Follow along as we take a quick tour of it.

Lightning Calendar for Thunderbird

Lighting brings two new tabs to Thunderbird. A Calendar tab, and a Tasks tab. The two are interchangeable with one another, especially since any task can be converted to an event and vice versa. The calendar view also shows events, the date, and multiple different views of as many calendars as you need to add.

Adding events to the calendar is easy. The New Event window offers empty spaces for all of the details, times, reminders, invitations, and any other info you might need to attach to it. You can also choose whether to make events public or private (depending on where your calendar syncs from).

The Task pane is less cluttered and simple, and you’ll notice that the sidebar now contains calendar Events. Adding a new tasks just involves typing it in, and then pressing the New Task button.

Unlike calendar events, tasks can have priorities, progress, and completion marked. Tasks can also be postponed, or transferred to a different calendar with ease.

Reminders can be set to go off at any duration desired prior to an event, or, when dealing with tasks, if the task isn’t completed. These reminders can be snoozed for a specific amount of minutes like an alarm clock, or it can be dismissed.

Within the Options tab the calendar offers a place to change default settings for reminders and other settings. This is particularly useful if you want Tasks to automatically have an alarm attached each time one is created.

Overall Analysis

When you combine all of the powerful features found in Thunderbird’s Lighting add-on, and its free price tag, it gives Microsoft Outlook solid competition. The calendar is effective, intuitive, and it doesn’t hog system resources on the computer it is running on. The main downside is that Lightning doesn’t work with the beta channel of Thunderbird, so you won’t be able to test the latest and greatest version with it. But if you’re happy running the most recent stable release, Lightning may be a calendar system worth checking out.

    I would agree with you…Thunderbird and Lightning are indeed a great piece of software.

    However…if you depend on a task manager (like I do) and really need it to be in sync with a Android smartphone, tablet, etc…then you might want to save yourself some grief and try something else. I’ve been researching and testing various “solutions” for more than three years. To date, there is still only one or two actually methods of syncing the Lightning Tasks with an application on the phone or other device, no one seems to be working on a sync with Lightning.

    The solutions I mentioned require one or more third and fourth party account or product and were not simple. For example (and this is from the support site for one of these products)

    Thunderbird/Lightning connected to a SyncML server (paid account).
    The SyncML connected to a Web-based Task Management app (monthly fee of course).
    Web app sync to an Android app, but only their proprietary app (which wasn’t great)

    I love Thunderbird and really want to use it all again…but after the first year with nothing…I was disappointed. Second year, I was getting miffed. Third year…want revenge. Now…I have officially given up and gone back to a plan cellphone and a 10 year old Palm Pilot that syncs great…plus my old paper planner. I’m back to happy
