Walmart Seller Key Events and Holiday Dates 2025

Q1 (January – March)

January begins the year with fresh demand. Consumers often act on New Year’s resolutions — fitness gear, health and wellness items, home organization, hobby supplies, winter apparel. Key days in January are New Year’s Day (Jan 1), Martin Luther King, Jr. Day & U.S. Presidential Inauguration (~Jan 20), and Lunar New Year (~Jan 29). 
For sellers, the early part of Q1 is ideal for clearing out leftover holiday inventory with promotions or discounts, updating product listings (titles, images, keywords) to reflect “new year” messaging, and ensuring that winter-relevant SKUs are well stocked.

February brings consumer behavior that often shifts a bit: winter categories remain relevant, but comfort, home, and indoor goods pick up. Key dates include Super Bowl Sunday (Feb 9), Valentine’s Day (Feb 14), and Presidents’ Day (Feb 17). During these, products in “gifts,” snacks, party supplies, apparel do especially well. Sellers should plan discount bundles, gift sets, or promos ahead of these dates, and ensure shipping cutoffs are clear — late shipping can kill reviews.

March is a transitional month. Not every holiday is fixed, but some known dates are: Mardi Gras / Fat Tuesday (~March 4), International Women’s Day (March 8), Daylight Savings (Spring Forward ~March 9), St. Patrick’s Day (March 17). Easter is not in March in 2025 (it falls in April), so spring inventory and marketing should begin ramping up later in the quarter. For March, sellers need to assess what worked (which winter sales, which promos), begin ordering or creating spring inventory, update visuals to lighter, more seasonal themes, plan for content/ads around spring events, and start mapping Q2 promos.

Q2 (April – June)

April is often quieter in terms of major holidays but still very important for setting momentum. Key dates include April 1 (April Fools’ Day), Easter Sunday (April 20, 2025), Earth Day (April 22), and Arbor Day (April 26). These days tend to drive purchases in decor, home goods, eco-friendly items, gardening supplies. In April, sellers should test smaller promotional campaigns, adjust inventory so that items for spring and summer are in stock, ensure lead times from suppliers are respected.

May heats up with Mother’s Day (May 11) and Memorial Day (May 26). These are high opportunity dates for gifts, beauty, fashion, outdoor/patio/BBQ gear. Sellers need to plan their promotional discounts early (at least several weeks out), prepare creative imagery targeting “mother,” “mom,” “memorial,” and consider bundles or gift sets. Also, because many shoppers begin holiday purchasing mindset earlier, start previewing summer deals and making sure inventory is positioned.

June carries forward summer momentum with Flag Day (June 14), Father’s Day (June 15), and Juneteenth (June 19). But perhaps more critical are the Walmart internal deadlines related to the “Summer Deals Event” (Walmart’s version of a Prime Day / deals week). According to publicly available info, for participation in the Summer Deals Event, sellers need to meet certain submission deadlines: the Deals portal opens; hero item lists lock; standard item submissions deadline; and critically, the WFS (Walmart Fulfillment Services) inbound deadline of June 2, 2025 for items to be fulfilled via WFS during the event. Missing those deadlines means losing considerable benefits of the event (visibility, fewer logistics delays, possibly better fee arrangements). So for June, make sure all promotional items are approved, inventory is in place, shipping logistics sorted.

Q3 (July – September)

July begins with the aftermath of summer deals events and includes holidays like Independence Day (July 4). The critical event here is the Walmart “Deals Event” commonly held in early to mid-July (for 2025, it’s expected around July 8-13) where Walmart runs large promotional campaigns on many products. Sellers must ensure hero items are set, discounted pricing meets minimum thresholds (standard vs hero discount rates), inventory is in WFS if using fulfillment, and marketing campaigns are live to capture traffic. This week can deliver large volume if properly prepared. After the event, evaluate performance, adjust pricing, restock fast-moving items, and reallocate advertising budgets.

August is strongly influenced by Back-to-School. Shoppers are seeking school supplies, apparel, dorm items, electronics. Also, August is typically a build-up month for Q4 — sellers should be auditing inventory, supplier lead times, warehousing, ensuring product content is refreshed, perhaps launching new SKUs timed for fall. August often includes slow points, so it’s a good window to test offers, flash promotions, and make corrections before Q4’s heavy traffic.

September marks the shift to fall and holiday prep. Labor Day (September 1) is a trigger for seasonal clearances of summer inventory and push of “fall goods” — jackets, outerwear, home decor, garden clean-ups. Also religious holidays like Rosh Hashanah (~Sept 23) can affect purchasing rhythms in communities. Sellers should have begun to list holiday/winter SKU assortments, ensure that products intended for holiday gifting are reviewed, content updated, logistics set for increased volume, and begin scheduling major promotional events in Q4 (bullets: Black Friday, Cyber Monday, Holiday Deals, etc.).

Q4 (October – December)

This is peak season for Walmart sellers. Many buyers make their biggest purchases between October and December; holidays, promotions, and deadlines all cluster.

October kicks off holiday shopping. A key date: October 1, 2025 is the deadline to add products to Walmart Fulfillment Services (WFS) if you want holiday shipping (so products can be delivered quickly during Black Friday / Cyber Monday period). Also in October there are several “Pro Seller badge refresh” dates (for example, October 5, October 20) when Walmart evaluates seller metrics — shipping speed, cancellation rate, seller performance. Having that Pro Seller Badge helps with visibility or trust. Halloween (Oct 31) also provides a surge in seasonal decor, costumes, treats. So in October sellers should finalize holiday-marketing calendar, ensure stock is in place (especially for WFS), confirm all product content is holiday-ready, ramp up advertising, ensure customer service / fulfillment operations are ready for increased volume.

November is dominated by Thanksgiving (Nov 27), Black Friday (Nov 28), and associated lead-in promotion efforts. Also important is the last day to qualify for Pro Seller Badge before Black Friday (Nov 20). Black Friday is perhaps the biggest revenue opportunity — deep discounts, high traffic. Sellers must have promotions, ad campaigns, inventory, pricing all optimized well in advance. Also monitor “Holiday Deals” or “Deals Week” events Walmart hosts. Additionally, ensure pricing competitiveness, shipping speeds, and reviews are strong, since competition is fierce.

December continues the holiday crescendo with Cyber Monday (Dec 1), extended gift-giving period (e.g. Hannukah Dec 14-22), Christmas Day (Dec 25), and end-of-year sales/clearances and New Year’s Eve (Dec 31). After Black Friday and Cyber Monday pass, there is still sales potential through gifting, last-minute shoppers, and clearance of slower SKUs. Sellers should plan for post-holiday returns, make sure customer service remains responsive, and prepare for the transition into Q1: set plans for post-holiday promotions, resolutions (fitness, health, organization), and carry inventory accordingly.
