How long in advance do you think you need to book a cake for a special occasion?

I’m wondering if I should publish clearer leadtimes on my website to help customers not be disappointed (I have already pinned a post about wedding cake availability for next year to try and help with this). I’d be grateful for your input really. Would you think:

A- one week or less
B -around 2 weeks
C- About a month ahead
D- about 3 months ahead
E- 6 to 12 months ahead
