This is what i mean with the Gov never plans things if you want to do this the right way before you announce you would make it impossible to book between those dates. would prob take someone about 1/2 a day to code and test it to make sure there's no issue, since its pure validation if the date is between this and that, no time available... or if you want to be hacky make the whole site pretend its the 2nd until the second so when its requesting the database for available times it won't show the weeks we are on lockdown. I Really hate how unprepared they are when they announce stuff like.
