I am looking for a data source / database that holds historical (10 years, better 20 years) dates of US and European stocks:

I need the historical date when the quarterly (or annual) fundamental data of that company was published in the past.

Solutions like Reuters or Bloomberg would possibly be too expensive... :-(

(I am posting this question at quant / stackexchange, too)

Try googling for quandl that site has lots of different data available for free.

Thanks for that hint.

I did that already but unfortunately without success: there is no historical date available at Quandl for German stocks.

And as an adendum to my initial posting:

I am looking for the

Historical German earning events of the past 10 - 20 years.

4-traders does have them, but only for one year, as it seems:

Yahoo finance seems to have it, too, but I am unsure about the data quality.
