Work backward from a demand date you verified using inventory count, prep time, daily listing capacity, and launch lead time to avoid missing the selling window.
Start the calendar now. Prep by 2026-12-03, start listing by 2026-12-17, and have the batch live by 2027-01-07.
Check exact-item sales by month in eBay Product Research. Use Google Trends only as relative search-interest context for the item and region. Record the date range and rejected comparisons.
Once the seasonal batch is scheduled, use the Best Listing Time Calculator to run controlled day/time tests instead of mixing seasonality with posting-hour claims.
There is no universal month for every item, platform, and region. Check historical sold performance for the exact product, choose a target demand date, and use this planner to get the batch live early enough.

It works backward from the seller-selected target date using live-before-target lead days, prep days, inventory count, and daily listing capacity. The result shows production and publishing dates plus schedule slack.
This calendar plans weeks or months of seasonal inventory production. The Best Listing Time Calculator helps test day and hour posting windows after the inventory is ready.
