implement an dayshours left on banners

[prisma shuttle]

Im sorry if I'm dumb or something, but I'm not great with hours and timezones. So, an bours left on the banners would be greatly appreciated.

i think there is actually hours for anything timed. But If it doesn't you can tell by the days it showed such as 2 day(s) = 2 + (<24 hours)
