Japanese TV schedule, 26 hours rather than 24 hours? (MORE INSIDE)?

So I was recently looking at a Japanese TV guide for the schedule timings of a show I like to watch, and I found out that its on TV on "金 / 26:00"

Friday at 26 o'clock if I am correct. But what is 26 o'clock??? Not sure what to make of this, does anyone know why this is?
