I have a sitemap where a lastmod
date is 1969-08-26
, the format is correct: https://www.w3.org/TR/NOTE-datetime , however Google says that it is incorrect.
Is there a min value for a date? I can not find any restrictions regarding this.

lastmod
field entirely. It's an optional field and Google has said that they don't usually pay attention to it because so few sites keep it up-to-date properly. See How important is it to include <lastmod> in a sitemap?1969-08-26
appears to predate the internet so that would seem unlikely?! (Why do you "have a sitemap where alastmod
date is1969-08-26
"?)1970-01-01
which seems to be accepted by Google.
