Are these scanned paper records? EHRs typically have a field for the date of service, so if this is unstructured as you say I'm guessing you are speaking of scanned records.
If scanned, have they been through OCR so you are working with text, or just the images?
More assumptions - it sounds like you have text. Next challenge is that dates can be part of a note, not just identifying the date of service. "Patient seen today for followup of appendectomy performed 5/1/2023" for example. Also, you would need to handle multiple formats - some people use 5-1-23, some use slashes, some put the year first.
Can you give more specifics?
