Zoroastrian calendar

Asha () or arta (; ) is a Zoroastrian concept with a complex and highly nuanced range of meaning. It is commonly summarized in accord with its contextual implications of 'truth' and 'right' (or 'righteousness'), 'order' and 'right working'. It is of cardinal importance to Zoroastrian theology and doctrine. In the moral sphere, aṣ̌a/arta represents what has been called "the decisive confessional concept of Zoroastrianism". The opposite of aṣ̌a is druj ().
