Real Cutoff
Official contest pages contradict themselves. This is when things actually close.
25 real prize contests — hackathons, jams, bounties — checked against their own official rules on 2026-09-26. Every deadline below is the earliest instant among every official source that states one, computed by deterministic time-zone tools, never guessed by a model.

Times are shown in your own time zone. Eligibility was checked for one adult entering alone from Nevada, USA; each contest page quotes the rule, so check it for where you live.
