native language support for around 30 languages. Those are mostly user-contirbuted, please contact me if there is a bad translation or you'd like your language added!

aCalendar only asks for mandatory permissions for its functionality: Read and write contact data for birthdays as well as read and write calendar data for events. 'Send Email to guests' is bound to 'write calendar data' by Google. NFC is for sharing events by touching another NFC-enabled phone, and requires manual confirmation.

Unfortunately app2SD cannot be supported, because homescreen widgets do not work from SD. This is an Android limitation. But aCalendar is optimized not only for speed but also for size.

♥ If you like aCalendar, please rate or comment and recommend it to your friends. Also now available is aCalendar+ for some extra features ♥

    Far the best of about five Calendars I tested, nearly perfect.
    A nice additional feature could be a fast switch form monthly to weekly to dayly view.

    Great calendar, but PLEASE add a bigger Widget, then it would be the perfect calendar!
