I get that. That can be frustrating. You could try asking family members, ask for a copy of your birth certificate, contact the hospital, try out this free natal chart rectification software, or hire an astrologer to rectify your natal chart (I can recommend Bracha Goldsmith). If you still don't know, we'll have to improvise a bit in the beginning (e.g., you can calculate a chart for every hour of your birthday and compare them) and use intuition to dive a little deeper. In the end, it's about getting to know yourself and letting go of what doesn't align with you. There's still lots to talk about and work with, even though you're not sure about your time of birth. Preferably schedule "Coffee with Daisy Deb" sessions, instead of readings, and let me know in the booking form that you're not sure about your time of birth.
