NIH Due Dates vs. Expiration Dates

National Institutes of Health recently published a post titled Clarifying Due Dates vs. Expiration Dates on Funding Opportunity Announcements. The expiration date is the day that the FOA “retires” (becomes unable to be applied to) and so proposals submitted on an expiration date will not be accepted, as that FOA is not active anymore. In contrast, the due date is the day that the proposal must be submitted to the sponsor.
