nested conditions?

I try to set up opening times for a client. normal times shall repeat once every week, infinitely. but furthermore there are holidays when the company is closed. instead of altering the normal times to display no time from x to y and instead display z, i wanted to do a nested thing like that:

[normal times / hide from x to y]
[normal time / mondays – show mondays until 2020]…[/normal time]
[normal time / tuesdays – show mondays until 2020]…[/normal time]
[normal time / wednesdays – show mondays until 2020]…[/normal time]
[normal time / thursdays – show mondays until 2020]…[/normal time]
[normal time / fridays – show mondays until 2020]…[/normal time]
[normal time / saturdays – show mondays until 2020]…[/normal time]
[normal time / sundays – show mondays until 2020]…[/normal time]
[/normal times]
[holidays / show from x to y]
[holiday times]…[/holiday times]
[/holidays]

but somehow it does not work. it’s still showing the actual normal time content and on top the closing tag [/normal times]

how do i get this working?
