The trading calendar is running your commercial strategy when it should be the other way around.
I see this consistently in ecommerce businesses at scale. The annual calendar is structured around peak trading periods, promotional moments, clearance events and seasonal campaigns. The team organises itself around the calendar. The budget flows to the calendar. The agency brief follows the calendar. And the longer-term structural work, the conversion architecture, the retention programme, the customer data infrastructure, the product discovery logic, gets perpetually deferred because there is always a peak coming and the peak always takes priority.
The trading calendar is a weather system and you are trying to do construction work in it. Every time there is a break in the weather long enough to start the foundations, the next front arrives and the tools go back in the van. The business gets very good at responding to the weather and never quite builds the structure that would make it less exposed to the weather in the first place.
The ecommerce businesses that break out of flat growth are not the ones that got better at peak trading. They are the ones that found a way to do the structural work in parallel.
