Not every deadline is a deadline
What are the different types of grant deadline?
Four, and they behave nothing alike. A fixed cycle deadline is a date, once or twice a year, and missing it costs you a year. Rolling means applications are accepted continuously and reviewed at intervals, so the real deadline is the review meeting you want to be in. Letter-of-inquiry-first means the published date is for a short screening document and the full proposal comes later by invitation only. Continuous or open means no date at all, which sounds generous and usually means the programme is competitive on readiness rather than on timing. Only 48% of the private foundations we publish carry any deadline at all, so for most of them the question is not when but whether they accept applications.

The four, and what each one asks of you
- Fixed cycle
- One or two dates a year, published in advance, hard. Most federal programmes work this way. Plan backwards from the date, and remember that the registrations and the letters have their own lead times inside your window.
- Rolling with periodic review
- Submit any time, decided at the next board or panel meeting. The published date is often the review meeting rather than a cutoff, so arriving a week before it is the same as arriving four months before it. Ask when the next review sits.
- Letter of inquiry first
- A short screening document against a published date, then a full proposal by invitation. Treating the letter as a compressed proposal is the most common way to fail this format: it is a screening step and the job is a clear statement of fit.
- Continuous or open
- No date. Usually means the funder decides as good applications arrive and the money runs out when it runs out, which rewards being ready over being early. Also the format most likely to be quietly closed without the page being updated.
What the filings show
Of the 19,390 private foundations published on this site, all of which accept applications, 48% carry a deadline in their filing. The rest operate on one of the other three patterns, most often rolling.
That is worth internalising, because the mental model most people bring from federal funding is the fixed cycle, and it is the least common pattern in foundation giving. Waiting for a date that does not exist is a real way to spend a year not applying.

Where Quillify comes in
Deadlines land on a calendar with the lead time attached rather than as a date you have to remember, and monitoring a saved search surfaces new matches as they publish, at 1 credit per run and whatever cadence you choose.
For the rolling and continuous programmes, which are the ones a calendar cannot help with, the answer is monitoring rather than memory.
Who asks this most
The answer above is the same whoever you are. What Quillify does about it is not.
