There actually is an easy tool for this. The tool is called MySteemitFriends.Online.

It should look like this:

Source: https://mysteemitfriends.online/upvotelist.php?voter=musing&author=jlordc&date=2016-03-30&toDate=2018-10-01

Just change my username to yours as well as the date you want to look at.

Remember to uncheck the "Exclude Comments" since Answers on Musing are treated as "comments" on the Steem blockchain
