Your first chart, step by step
How DrAstro works: from birth details to your reading
Enter your birth details, calculate a chart, then explore the placements and explanations. You can start with the free core chart without signing up. Here is what to prepare, what each step does, and how to read the result.
By DrAstro · Updated
Free core chart. No sign-up needed. Birth time is optional.
1. Enter your birth details
Add your birth date and search for the city or town where you were born. Choose the matching suggestion, checking its region or country when places have the same name. Use your birthplace, even if you live elsewhere now.
If you know your birth time, enter the local clock time recorded for the birth. Check AM and PM carefully. If you do not know it, leave it blank. An estimate should be identified as approximate rather than treated as exact.
2. Calculate the chart
Select “See my chart” after completing the required details. DrAstro uses Swiss Ephemeris to calculate celestial positions and builds the chart view from those positions and its astrological settings.
Vedic and Western views commonly use different zodiac reference frames. That can change sign placements without changing the birth details. The Vedic and Western chart comparison explains what to check.
3. Start with the placements and story
Explore your Sun, Moon and rising sign, then the chart factors that interest you. The general story introduces themes from the chart. A dated reading adds the period it covers, so check whether you are viewing today, a month or a longer outlook.
Where an insight offers “Why this applies to you,” open it to explore the chart factors behind the explanation. You can begin with everyday questions about work, relationships or routines; you do not need to learn every astrology term first.
What if you do not know your birth time?
You can still start, but the Ascendant and houses are time-sensitive. Some placements may be uncertain within the birth date. Keep that uncertainty in view, and update the details if you later find a birth record. Our birth chart guide explains how to prepare the information.
What is free?
The core chart calculator is free without sign-up. Additional readings, saved-account features or paid services may require an account or purchase. Check the information shown for each feature before choosing it.
How the reading is produced
The astronomical calculation and its astrological interpretation are separate parts of the process. The methodology page explains the calculation inputs, chart settings and interpretation. For a quick overview that does not use your full chart, you can also browse today's sign horoscopes.
