Which week this spring is good for signing a lease?
Look at April 8–12. Jupiter trines the ruler of your 4th house, the house of home, and the Moon is not void of course on the 9th and 10th.

Is the birth chart really free?
Yes. Your natal chart, wheel and a short plain-language reading are free forever, with no signup and no card. Paid plans add the full reading, longer forecasts, planning tools and pro techniques.
What do I need to make my chart?
Your date, time and place of birth. The time matters most for your Rising sign and houses.
I don't know my birth time. Can I still use it?
Yes. Tick "I don't know my birth time" and we'll build the chart for noon. Planet signs and most aspects stay reliable, while the Rising sign, houses and the Moon's exact degree are approximate, and the reading says so. If you know roughly when you were born, Pro's rectification tools can help narrow it down.
How accurate are the calculations?
We use the Swiss Ephemeris, the standard for professional astrology software. Planet positions are accurate to within an arc-second, and time zones and daylight-saving history are handled automatically.
What is the assistant?
A chat inside the app that answers questions about your chart and your days in plain language, can show the calculations behind its answers and can add a date to your calendar. With a free account you can ask 30 questions a day, 150 on Basic, and Pro has no daily limit.
What's the difference between Basic and Pro?
Basic is for living with your chart day to day: the full reading, forecasts for the month and year, best days, compatibility, astrocartography and all eight reports. Pro adds the professional toolkit: progressions, directions, returns, horary, rectification, Vedic charts, fixed stars, midpoints and more.
How does the free trial work?
You get 7 days of Basic, with no credit card needed. When it ends, you stay on Free unless you choose to subscribe.
Are the PDF reports a subscription?
No. Each report is a one-time purchase ($9.99, or $14.99 for Your year) that is yours to download and keep. They are also included in Basic.
Is my birth data private?
Your birth data is used to calculate your chart. To write your reading, reports and calendar forecasts, our server receives your birth date, time and place. Your account keeps saved charts, your reports and assistant chats (for 90 days). Messages to the assistant are also processed by our AI provider to write the answers. We never sell your data, and you can delete saved charts at any time.
Do I need to install anything?
No. Astrodamus runs in your browser on phone, tablet and desktop. You can also install it from the browser, so it opens like an app and can send you a morning forecast.
Which house system and zodiac do you use?
Placidus and the tropical zodiac by default. You can switch to Whole Sign, Koch, Equal and others, or to sidereal and Vedic charts on Pro.
