May 2019: MOBS (A Month of Big Sundays)

As you may know, Big Sunday started in 1999 as a single day of service known as Mitzvah Day. A small but mighty team lead volunteers to complete 19 different projects helping seniors, homeless, shut-ins, the environment and more! This continued each year, and continued to grow and grow, and eventually outgrew the one day and became Big Sunday Weekend! Then, that was so popular that we even outgrew the weekend and we’ve become an independent nonprofit offering more than 2,000 ways for people to help 365 days a year! Still, our biggest event remained Big Sunday Weekend in May, an incredible three-day festival of helping.

In 2016, we realized that we couldn’t fit all the projects we wanted to do in just one weekend, so we expanded Big Sunday Weekend into MOBS! (A Month of Big Sundays) during which we partner with many great local nonprofits and schools to host and support events every day in May! This has allowed us to take on even bigger projects, reach more people, make new alliances, and more easily fit in with everyone’s (and every organization’s) busy schedules. As Big Sunday enters our 20th year, A Month of Big Sundays remains our biggest month of helping!

The 2019 Application Form is open for submissions! If you’re a nonprofit or school, we look forward to working with you and seeing the many diverse projects and activities that will connect and help thousands of people.

Sign ups for volunteers will begin on Monday, April 1st.
