I find divining for numbers and names and words really inaccurate! randomly you get a hit but it's really unreliable!
I saw your thread in astrology SB, check out
Ivanna's in that area recently about finding her birth time for her chart. If you can get the client to get a copy of her birth certificate (the long version or the more expensive original one, not the short other one). Sometimes in our countries though they don't record the time
They could also ask family / close family friends if they can remember the time of birth. That is the most accurate way of doing it.
If you have to divine it, put numbers out on paper and see where the pendulum swings on them. You could use tarot / oracle cards and see what numbers come up. Could you ask for the birth time and dream it? there was a thread about dreaming of exact dates / times recently
