No birth time? Here is exactly what you can and cannot say

Most chart tools quietly default to noon when the time is missing and then present the result as if it were exact. That is where bad readings come from.

Still reliable

Sign placements for the Sun and the slower planets are safe across a whole day. So are most aspects between them, and the chart's element and modality balance. That is already the majority of the interpretive material.

Unreliable

The Ascendant, the Midheaven and every house cusp are functions of the time and the place. With no time, all of them are guesses. Anything phrased as 'in your seventh house' is unsupported.

The Moon is the borderline case: it moves twelve to fifteen degrees a day, so it can change sign within a single date. Check the boundary before committing to it.

What to do instead

Read the chart as a whole-sign sketch, tell the listener which parts are provisional, and treat the birth certificate as a genuine research task worth doing. Rectification is a real technique, but it needs events to work from — not vibes.

Put this into practice on a real chart — free, no account needed.
