If you were born on March 21, your Sun may be in Pisces or Aries: it depends on the year, time and birth time zone.

Computed: Tue, Oct 13, 2026, 9:51 AM (UTC). Display zone: UTC.

Ranges computed over the whole local day in 1950–2030, not an exact natal position. Another time zone can move the crossing to an adjacent date. Chaldean decans: three 10° sectors, with traditional rulers cycling Mars, Sun, Venus, Mercury, Moon, Saturn, Jupiter.

The Sun in Pisces finds personal expression in images, compassion and the shifting edges of imagination.

Sensitivity absorbs a place's mood. With the Sun in Pisces, you may recognize yourself in music, a story or closeness to someone going through difficulty. Imagination is fertile, but distinguishing your own desire from surrounding expectations can take time and a quieter setting.

With the Sun in Aries, bold beginnings, open competition and candor help you recognize your own direction.

Initiative comes before permission. The Sun in Aries gives identity a direct, competitive character: an empty road appeals more than an established route. Impatience accompanies the wish to find out immediately what you can do, rather than planning every step in advance.
