linux default iconThunderBirthDay Publisher's description

Display birthdays from the Thunderbird addressbooks as events in Lightning

ThunderBirthDay is a Thunderbird extension that display birthdays from the Thunderbird address books as events in Lightning.

Quick install:

Install Lightning, MoreFunctionsForAddressBook and ThunderBirthDay, then create a new local calendar choosing ThunderBirthDay as provider.


The Lightning extension needs to be installed, as well as an extension enabling the fields "birthday", "birthmonth" and "birthyear" in the address book. The only extension I know that does this is MoreFunctionsForAddressBook.

How to use:

Create a new calendar in Lightning by clicking File>New>Calendar... in the menu bar. Then choose "On My Computer" as location and "Birthdays from the Thunderbird addressbook" as type for your calendar. Also specify the address book to use as a source for birthdays. Finally choose a name for the new calendar.

Now open the "Edit Card" dialog of an address book card and set the birthday in the "Other data" tab. Note that these changes don't take effect in the calendar until it gets reloaded. To do this either restart Thunderbird or right click on a calendar from the list, then choose "Reload Remote Calendars".

Also note that the events generated by ThunderBirthDay cannot be modified with Lightning for the moment. Maybe future versions of the extension will be bidirectional.

Any questions?

If you have any questions about how to install or use the extension, about technical details, bugs or anything else, please let me know! Suggestions for new features are also very welcome! Just send me a mail to thunderbirthday@(mydomain) replacing (mydomain) by ingomueller.net.


If you wish to add a translation for a new language or if you found a mistake in an existing one (including the one in English), I'd be really glad, if you could have a look at the translation portal Babelzilla. Thanks a lot!
