The center will be open for people who live and work in Detroit from 7 a.m. until 4:30 p.m. this week and next week, including Christmas Eve and New Year's Eve.
The city's Chief Public Health Officer Denise Fair Razo said the testing site was originally going to be closed those days but decided it would be important to give people the chance to get tested before gatherings.
"We want to make this really easy and simple for Detroiters," she said.
Tests are free and there is no limit to how many will be conducted at the rec center. People who will attend several gatherings are encouraged to get tested several times.
Fair Razo said people will get their test results within an hour.
