Lots more.
From the date of birth (DOB) you can find your "Life Path" number by adding the numbers of the date of birth.
Your life is divided into 3 Cycles which can predict the major changes, transitions & phases of your adult life. This is taken from your DOB and the astrological cycle of the moon (28 years and 4 months).
Also you have 4 pinnacles which divide your life into 4 parts just like the 4 seasons. The Spring of child hood, the Summer of youth, the Autumn of middle age and the Winter of retirement.
I learned numerology a few years ago and it predicted exactly the years I made the biggest changes in my life.
Wish I'd learned it when I was younger.
You can combine your name and DOB to get your "Essence" which gives insight into more subtle influences in your life.
For relationships, numerology can be used to give insight into compatibility, best time to meet someone, marry and which years will be the hardest, most fruitful and fertile etc.
It's all here on this web site which is free to use with calculators to do all the hard work for you.
(Including relationship compatibility using numerology and astrology based on date of births)
