You can export this data at any time by clicking into the individual hashtag profile. Note that the 'Last calendar month' option will only be available once you've been tracking your hashtag for over one calendar month!
From there, you have the ability to export Current month or Last calendar month. (We do not hold tracked hashtag data for longer than two calendar months.) We recommend scheduling a monthly report (instructions here).

**REMINDER- Hashtag tracking data is only available from the day you start tracking your hashtag.
