About a day and a half, and I do it every year when we go to Florida. We always get to the airport in the morning so I'd wake up any time before 8 o clock, and I won't sleep till we the next day in the evening even though we usually get to our hotel in the afternoon. Alas, I can't sleep on planes and when we arrive, we resist the urge to sleep to get our body clocks adjusted ASAP.
Any other time, it wouldn't happen, I can hardly go 18 hours without sleep, nowhere near 24 hours.
