Are there good math programs in NYC that run in the afternoon this summer?

Hi, I’m a junior living in NYC. I’m wondering if there are good math programs that run in the afternoons that are available this summer. I’m already enrolled in NYU Math Circle, which runs from 10am-3pm over 7/17-8/3. I’m also looking into a different math program that, if I get accepted into it, will occupy most of my earlier summer time. Is there a solid NYC math program that runs after 3pm from mid-July, or one that starts after July? Thanks.

edit: To clarify, I’m willing to attend a math program outside of the city as long as it starts after July. There doesn’t seem to be many programs that start so late in the summer, though.
