Annora Sky is a free birth chart calculator — enter your birth date, time, and place to get a full natal chart, no signup needed. Start with your Big Three (Sun, Moon, Rising), then explore planets, houses, and aspects. Unlike a one-time reading, it tracks live transits against your chart, so there's a reason to come back — see what's active now. Synastry/compatibility charts included. Charts saved privately in your browser.
