National Day Calendar announced the founding of National Secondhand Sunday to be celebrated the Sunday after Thanksgiving. This new National Day was submitted and approved in 2022 on behalf of Poshmark, the leading social marketplace for resale and secondhand items. Poshmark has taken charge of the social marketplace by empowering sellers, while giving buyers a more sustainable and unique alternatives during the holiday season and beyond.
After establishing National Secondhand Sunday, Poshmark has set out to highlight the economic and environmental benefits of choosing secondhand items during the holidays. The company is fostering the movement to instill sustainable shopping habits year-round. They chose the Sunday after Thanksgiving because it lands within range of the biggest shopping days of the holiday season–Black Friday, Small Business Saturday, and Cyber Monday. In addition, Sunday is the busiest shopping day for Poshmark, so it was fitting to choose celebration of this National Day on a Sunday, too.
