Birthday Calendar Exporter for Facebook

With this extension you will
- Follow and never miss your Facebook friends' birthdays.
- Generate and export a calendar with all your Facebook friends' birthdays.
- See number of your friends having birthday today at the extension "cake" icon.
- Have a birthdays' calendar overview.

The birthdays calendar can be exported in `ICS` format.
Dates of birth can be downloaded as the `CSV` file as well.

* ICS is a universal calendar format used by Microsoft Outlook, Google Calendar, and Apple Calendar.
* CSV file format used by Microsoft Excel or Google Sheets.

At the end of the process a file named `birthday-calendar.ics` will be downloaded automatically to your Downloads folder.
Use the generated file to import your friends' birthdays to your favorite calendar program.
I strongly recommend creating a new Birthday themed sub-calendar and use it for imports.

FAQ
Question: I have accidentally exported birthdays to my main calendar, how to reverse it?
Answer: Only Google Calendar properly supports event removal. Head to the "Download Calendar" tab and use "Delete Imported ICS from Google Calendar". A file named `delete-birthday-calendar.ics` will be downloaded. Import the file to the respective calendar.

Question: Is it possible to remove some of the contacts before importing to the calendar?
Answer: There is command line tool you can use: https://github.com/guenter-r/calendar_file_splitter
