2026 Amazon Seller Calendar: Inventory Order Dates
A 2026 Amazon seller calendar built for inventory planning: the events that move demand and the lead-time-back dates to order for each.

Frequently Asked Questions
- What are the key dates on the Amazon seller calendar?
- The demand peaks are Prime Day (typically mid-July), the fall Prime deal event (around October), and Black Friday and Cyber Monday into the December holidays. The operational dates that matter for inventory are the deal submission deadlines and the Q4 storage and capacity changes, which fall weeks before the demand peaks themselves.
- When should I order for each Amazon event?
- Subtract your full lead time from the event. If Prime Day is mid-July and your lead time is 80 days, order in spring. The calendar that matters for inventory is the set of order-by dates, not the event dates, because ordering on the event date means the stock arrives months too late.
