Pass once can pass only once, as it's name says, but if you want you can reset it with the Reset block that can be found in the same category. Of course it matters where the Reset block is placed!
"Once a day" under "on Tick" can be used to cause the reset block to run at 00:00 every day. Or combination or "Hours Filter" and "Once a day" blocks.
Note that Pass once has it's own memory and know whether it passed or not, but in case the EA is restarted, the block will be reset as well.
