Most students discover their dream summer program in April — a month after its application closed. The single highest-leverage planning move is knowing when deadlines actually fall. We pulled the deadline month for every one of the 1,599 programs in our catalog. Here is the shape of the year. ## The deadline year at a glance | Month | Programs with deadlines | |---|---| | January | 178 | | **February** | **267** | | **March** | **303** | | April | 131 | | May | 74 | | June | 47 | | July | 18 | | August | 9 | | September | 33 | | October | 89 | | November | 76 | | December | 158 | Two facts jump out. First, **February and March together hold 570 deadlines** — more than a third of the entire year. Second, the year has a *second* wave: October through December carries 323 deadlines (fall competitions, scholarship cycles, and early summer-program rounds). ## What each season means for you **September–November: research and shortlist.** Fall deadlines ([October](/extracurriculars/deadlines/october), [November](/extracurriculars/deadlines/november)) are mostly competitions and early scholarship rounds. This is also when you should build your summer-program shortlist for the winter wave — and line up teachers for recommendation letters before they're buried in requests. **December–January: the selective-program window opens.** [December](/extracurriculars/deadlines/december) has 158 deadlines, including some of the most selective research programs. Winter break is your essay-writing window. **February–March: the main event.** The [February](/extracurriculars/deadlines/february) and [March](/extracurriculars/deadlines/march) pages list hundreds of programs each. Treat these two months like finals for your summer: calendar every deadline, submit early (portals crash on deadline day every single year), and confirm recommendations went through. **April–June: the honest second chance.** Missed the wave? [April](/extracurriculars/deadlines/april) still has 131 closing dates and [May](/extracurriculars/deadlines/may) 74 — late-cycle programs, essay contests, and rolling admissions. Selection is thinner but real. **July–August: plan, don't apply.** With only 27 deadlines combined, summer is for doing the activities — and for prepping next year's applications while everyone else waits for September. ## Three deadline rules that save applications 1. **Deadlines repeat.** Almost every program runs an annual cycle, so this year's calendar predicts next year's. A freshman reading this in April isn't late — they're ten months early. 2. **Verify on the official site.** Dates shift by a week or two between cycles. Every listing on ExtracurricularHub links to the official page and shows when we last verified the deadline. 3. **Rolling means early.** "Rolling admissions" quietly favors early applicants. Treat rolling programs as due immediately. *Deadline counts from the ExtracurricularHub catalog, July 2026.
