Twitter Advanced Search
Be sure not to miss that Twitter has an advanced search tool that you can use to filter down anyone's Twitter feed to a particular date range. See: https://twitter.com/search-advanced?lang=en , where you can login to your Twitter account. Enter the account name you want to search through in the field labeled, 'From these accounts'.
. . .then scroll down and enter a date range at the bottom of the search tool interface.
A search can also be run in the main Twitter search tool in this format:
(from:PolatCanRojava) until:2020-04-01 since:2014-11-01
Be sure to click on the 'Latest' tab to get the full results. On the 'Top' tab the search results will be cut off.
