Yes - it starts at 7 AM, not PM!
This organization called Daybreaker throws these morning dance parties once in a while where there's no alcohol, people are encouraged to dress up in wild costumes [optional], and they just party it up before work on a weekday! Talk about seize the day ;)
You can read more and get your ticket here: [early bird discounts going on right now. They usually sell out, so I'd recommend getting it at least a week in advance]: https://www.daybreaker.com/city/bos/?_ke=eyJrbF9lbWFpbCI6ICJhbGx5bGFtdW1pY2hAZ21haWwuY29tIiwgImtsX2NvbXBhbnlfaWQiOiAiY3h6ejZaIn0%3D#get-tickets
