Timing isn't just about the day of the week; it’s about the calendar. For holiday inventory, the "Expert From India" advice is to list at least 3-4 weeks before the actual holiday. For example, Christmas decor should be live by late October. This accounts for shipping times and early-bird shoppers. Monitoring seasonal shifts ensures you aren't trying to sell winter coats in July or beach gear in December, keeping your sell-through rate healthy and your inventory moving.
