What disagreement can you possibly have with science that has proof???

Midsummer day is not a scientific concept. It is a traditional date,
like Christmas Day. It is therefore not provable by scientific means
(other than by the methods of historical research to determine when
people in the past have celebrated it).

You have not presented any evidence to show that Midsummer day has been
traditional observed at the summer solstice, only evidence that the
summer solstice is on 21st June. That was not in dispute.
