the major events won't change times. The "General Schedule" on the homebrewcon website at least is for '20, not last year.

These things don't change that much and are fairly dependable for those trying to figure out their travel schedule.
For actual seminar schedule, understand that acceptance/rejection notices for seminar proposals literally went out
yesterday.
It will take time for people to confirm, and the AHA to create a schedule for what seminar is when.
On the subject of seminars, my mead seminar was approved. The Cider Panel seminar was also approved and I'm on that too. And I'm planning to join a third seminar on the topic of judging/scoresheets. Supporting both KCBM and AMMA booths during Club Night too. Busy Busy. I bring my A-Game when it comes to sharing my stuff and I hope others do as well.
hope to see you all there
cheers--
