Welcome to Ohotto.com’s free birth chart service!

Here is the information that you’ll need to cast your birth chart: Exact birth date, time, and place.

Birth Time
Most birth times can be found on your birth certificate. If you can’t find it there – you may opt to order, from your birth hospital, the ‘long form’ of your birth certificate which may have it listed. Failing that, the next best option is to ask your parents or relatives if they wrote the time down or remember it.

If you simply don’t know your birth time, select the ‘Unknown’ option.

About This Birth Chart
This birth chart is based on the Western Tropical Zodiac using the Placidus House System. It will also come with a listed break down of planetary placements, house cusps, and planetary and angular aspects.
