Patricia, the link that you referenced in the first source was broken so I fixed it. That baptismal record entry is item #24. The only date that I see in that entry and which appears to be the birth date is 19 Feb. The year of 1702 is on the prior page. It's different than the birth year in the profile (1685), so you may need to investigate further to resolve the discrepancy.
There doesn't appear to be any location info in either page for where the event took place other than Ancestry's collection info: OstPreussen > Angerburg.
EDIT: As Helmut mentions below, the Feb 19 date may be the baptismal date.
