Mark your calendars! #GivingTuesday this year will be on Dec. 1, 2015.

The movement was started by philanthropists in 2012 as a way to help nonprofits across the country raise money by piggybacking on the energy of the holiday shopping season. #GivingTuesday is always on the first Tuesday after Thanksgiving. Charities, donors, businesses, and community groups are encouraged to use the hashtag and branding materials to promote philanthropic giving among friends, family, and co-workers.

Unlike The Seattle Foundation’s GiveBIG, no prior registration is necessary. #GivingTuesday isn’t a formal event. It’s a movement to use crowdsourcing to your nonprofit’s fundraising advantage.

If your nonprofit wishes to participate in #GivingTuesday, we have a few tools at your disposal. On Nov. 9, 501 Commons co-hosted a training session with SeaTech4Good in which attendees learned some useful tips in maximizing their Giving Tuesday campaigns.

You can also check out this infographic that lists 10 ways to building a winning campaign – which are also helpful for online giving campaigns in general. This document lists articles and web links that you should incorporate into your fundraising strategy. The organizers of Giving Tuesday also have helpful tools to get you started.

Good luck!
