Family Night

Just trying to see other think, so I can either change my mind and feelings, or whatever. Need advise.

I do: Bed time for kiddo's 9pm. (5 Kids, Ages Toddler To Fresh Teen).

I do: Dinner from 5-6.

I do: Kids clean their messesand kids showers/baths at 8p

I do: Kids help clean up dinner when dinner is over.

Spouse is very last minute, and on school weeks it creates lots of extra chaos in the home when spouse wants to make last minute (family night)

game plans, movies.

The kids aren't able to get done what they should because it gets forgotten (left for these plans) and the kids get on funky sleep schedules bc of it and also sleep in school bc they are tired. School nor I can get spouse to understand. Instead spouse stated that they feel doing that makes life boring and with chaos.

Please give me advise and help me!

And am I and school in the wrong? What how should this be? Advise needed
