text: my b-day is 12-10-81, his is 5-10-79, are we compatible?   not enough information for an accurate chart i'm afraid. the best web site for this sort of thing is at the bottom of this answer.  you'll need birth date, time and location for an accurate chart, however you can get an approximation without the birth time if it's the best you've got.  i was sceptical when i first came across this site. i have since been impressed time and time again. enjoy it, but don't take it too seriously. remember it's all someone elses interpretation, so it can't be entirely true...  ...but it's close!  best way to find out is spend some time together first and then, if you feel it's going well and would like to understand the relationship deeper, suggest looking at the site together. his response will tell you what you need to know. ;)
