Best times to watch
Every opening our scanner has recorded for this permit — 190 of them — by day of week and time of day (Pacific time). An opening is a date that went from closed to open. Dates closing are not counted here, and they make up most of what an availability change is. Darker cells mean more openings landed in that window.

JMT Yosemite drop report questions
How often does JMT Yosemite availability actually move?
Our scanner has recorded 35,033 availability changes for JMT Yosemite since it started tracking, broken down by month above. A change is any shift in the open-date set, so it counts dates closing as well as dates opening. Openings are counted separately, and on a different basis — 190 moments where at least one date went from closed to open. That is what the grid above plots, and it is why the two numbers do not add up to each other.
When is the best time to check for JMT Yosemite cancellations?
The grid above is built from every opening our scanner recorded for JMT Yosemite — dates that went from closed to open — bucketed by day of week and time of day in Pacific time. It's real detection history rather than a guess, and it's a rough guide rather than a guarantee.
How fast will I find out if a JMT Yosemite date opens up?
Paid plans are scanned about every minute with alerts within seconds. Free accounts are scanned hourly. Either way, PermitSnag catches the change — you don't have to refresh the page yourself.
