Has the COLT 2027 call for papers been released?
Not as of the last review on August 28, 2026. The COLT 2027 organizers had not posted a call for papers or an official submission deadline, so the date shown on this page is projected from the previous COLT cycle and should be treated as a planning estimate only.
What time zone does the COLT 2027 deadline use?
COLT uses Anywhere-on-Earth (AoE, UTC-12), like most AI conferences. An AoE deadline has not passed until the date is over everywhere on the planet, so you effectively have until 11:59pm on that date in the UTC-12 time zone. Every countdown on OpenCurious is computed in AoE.
Where is the official COLT 2027 call for papers?
There is no COLT 2027 call for papers yet. When it is published it will appear at https://learningtheory.org/colt2027/, which is also where COLT posts whatever has been decided about 2027 so far. OpenCurious tracks the date but is not affiliated with COLT; the official site always wins if the two disagree.
Is COLT 2027 the same as Conference on Learning Theory 2027?
Yes. COLT 2027 is also written COLT2027, Conference on Learning Theory 2027 — these are alternate spellings, abbreviations and common misspellings of the same conference, Annual Conference on Learning Theory. "DDL" in these searches is shorthand for deadline.
