With all monthly badges (Power Month, The Usual) you must be a member with Untappd for at least 30 days. This way we can accurately see your monthly totals. Even if you hit 30 beers at day 2 - don't worry - you'll get the badge on Day 31 (once you log in a beer). Remember, this badge is "moving window", so you if you don't check-in after 30 days, your window changes. Make sure you check-in on the 31st day, otherwise it won't work! If you have any questions or concerns - feel free to reach out to us at firstname.lastname@example.org.
