planets passing through signs in the past

Does any-one know of some-where to find out when the planets moved through the signs in the past years? Like, when Leo Moon switched over to Virgo Moon in September of 1998, for example? Just random. Is there an online source to find things like this? It is in a book I have, but it’s very general, just by months, no dates or times. Any information you have would be helpful! Thanks.

Yes, Any online ephemeris will give you planetary positions for the past -
