Google Sheets count consecutive dates

I have a Google Sheet with a list of dates & times like this:

10/24/2019 4:25:00
10/29/2019 4:33:22
10/30/2019 4:33:11
10/31/2019 4:24:11
11/1/2019 4:36:11
11/2/2019 5:21:37
11/4/2019 5:30:20
11/6/2019 5:21:28
11/7/2019 5:27:07
11/8/2019 5:22:34
11/10/2019 8:51:13
11/11/2019 5:26:27
11/11/2019 11:41:27
11/12/2019 5:27:49
11/13/2019 5:30:34

I am looking for a way to figure out the longest "streak" of consecutive dates where there was at least one entry. The data can be unsorted or sorted.
