On this page, you can find various statistics relating to the Half Dome permit lotteries to help you make an informed decision when you apply for the lotteries. While the statistics give you a sense of which days have lower or higher odds, they don't necessarily predict success rate this year.
The chart to the right shows the distribution of the preseason Half Dome permit lottery requests by day of the week.
The set of bar graphs below show how many permits have been requested for each date during the last Half Dome season. This graph shows actual number of permits requested for each day (225 permits are available each day). This graph shows the worst-case scenario for each day because each application will have only one of its permit dates filled (applications can have up to seven different dates requested).
