The annual day of non-stop fundraising is almost here.

At midnight May 3, Silicon Valley Gives begins its massive fundraising campaign, when online donations will be accepted for 24 hours in support of over 1,000 nonprofits from around the Bay Area. The fundraiser gives nonprofits the opportunity to raise millions of dollars in the span of a single day.

Since its inaugural year in 2014, 30,000 individual donors have raised a staggering $15.8 million to benefit charities in  San Mateo, Santa Clara and San Benito counties. This year, nonprofits from the San Francisco area have been invited to join the fun. Anyone is welcome to donate and donations are tax deductible.

Organized by the Silicon Valley Community Foundation (SVCF), which has been on the receiving end of massive donations by Mark Zuckerberg and others, this year’s event is being sponsored by Microsoft and NBC Bay Area. SVCF has, more or less, set the bar for nonprofits as the largest community foundation in the world.

Silicon Valley Gives is an opportunity to help nonprofits not only raise money but to teach them valuable skills to grow their organizations in the future. To date, 1,800 nonprofits have attended free trainings while bringing together thousands of donors, volunteers and local businesses to help the community.

The 24-hour race to raise funds will help a variety of causes, including assistance for senior citizens, the homeless and animals in need. Nonprofits looking to sign up can find more information here, and information about donations can be found here.
