Lucky days by birth date
Lucky Days Calculator
Enter your birth date, time and place to get lucky days based on your natal chart — a luck score from your real planets and houses, not a one-size-fits-all sun-sign reading. Astronomy, not numerology.
Watch it find one
The same chart, run against three real months of sky. The search stops on the days the rulebook actually marks — and shows the transits that put them there.
What you’ll get from your birth date
Your date, time and place of birth fix your natal chart. From there we score each day by how the moving planets aspect that chart — for love, money, work and energy — with the exact reason behind every score. Here’s a real example of one scored day:

Lucky days by birth date — FAQ
- How do lucky days by birth date work?
- Your birth date, time and place fix your natal chart. We then score each day by how the moving planets aspect that chart — so the lucky days are yours specifically, not your whole sign’s.
- Why is this better than a sun-sign horoscope?
- A sun-sign horoscope is one reading for a twelfth of everyone. Scoring against your full birth chart uses all your planets and houses, so two people born the same week can get different lucky days.
- What if I don’t know my birth time?
- You can still calculate a chart — the planetary aspects work without it. Adding your birth time sharpens the house-based scores for love, work and energy.
- Is the calculator free?
- Yes. Building your chart and backtesting past dates costs nothing; only the forward timeline is paid.
We build your natal chart with the Swiss Ephemeris, place it in Placidus houses, then score each day by how the transiting planets aspect your chart — per life area, 0 to 100, with the exact reason. It is astronomy applied to your birth chart, not numerology.
The rulebook encodes that tradition whole — four centuries of transit doctrine, written down as rules you can read, not a model that guessed. Read the methodology.
