Across 30 documented cases, Google and Bing are the only major sites that dress up for both Halloween and the winter holidays
Asked:
“Which major websites decorate their pages for seasons such as Helloween and Winter Holidays?”
Web research surfaced 30 well-corroborated website-and-season examples — 10 for Halloween and 20 for the winter holidays — spanning search engines, social platforms, developer services, and national retailers, each documented by at least two independent source hosts. Treatments range from playable Doodles and spooky interactive homepages to animated snow, gift-guide modules, and full seasonal art direction. This is a documented shortlist, not an exhaustive census of seasonal decoration.
Halloween (10 sites) Winter holidays (20 sites) — bar length is the number of independent source hosts documenting the decoration (square-root scale; hover a bar for the described treatment)
Google is the single most corroborated example in both seasons: 105 hosts document its Halloween treatment and 66 its winter one. ffcampaignforchildren.org
Bing goes beyond a logo swap: a 2013 horror-movie homepage with six hidden film Easter eggs, and 31 daily holiday surprises including animated snow in December 2016. news.microsoft.com
Google, Bing, and YouTube are true interface theming; most winter-holiday retail examples — Sephora, J.Crew, L.L.Bean, Fitbit — are seasonal homepage art direction and gift-guide merchandising rather than recolored interfaces. blog.hubspot.com
Independent corroboration is nearly even across seasons — 157 host mentions for Halloween vs 159 for winter — but Halloween's are concentrated in a few platforms while winter's spread across 20 sites. revistasdemo.untumbes.edu.pe

Documented shortlist of seasonal website decoration compiled from broad web searches across official archives, company and news pages, design roundups, and historical coverage; 30 website/season rows retained only when backed by at least two independent source hosts (16 hosts total; no single URL backs more than 30% of rows). "Hosts" counts independent source hosts corroborating each example; "major" is qualitative. Example years span 2009–2023; long decoration descriptions are shown in full in the table.
