Submission
Slips
Five open CFPs, filed as ruled slips below the fold — soonest deadline first. The big-name circuit (Techorama, NDC London/Oslo, DDC Cologne, BASTA!, Update Conference Prague, ESPC) is already stamped shut and filed at the bottom of this page.
Four of the five stamps below are punched in local Central European time (CEST). One is not: .NET Conf Community Days quotes its deadline in US Pacific — 6 Oct 23:59 PDT reads like a whole extra day of runway, but it actually lands at 7 Oct 08:59 CEST. Same clock, different stamp.

Techorama Belgium 2027
No 2027 dates or CFP posted yet as of 20 Sep. Historically the CFP for the May edition opens around November. Watch closely from late October.
BASTA! Frankfurt 2027
1–5 Mar 2027, Frankfurt — dates confirmed, site only says "Stay Tuned" for the CFP. Given the March date, an Oct–Dec 2026 opening is plausible but not confirmed.
Update Conference Krakow 2027
2–3 Jun 2027, Kraków — confirmed on a conference aggregator, but no CFP page is live yet.
Global Azure 2027
No central CFP — a federation of locally-organized one-day events (typically April). Each city chapter runs its own informal call, usually opening Jan–Mar.
NDC Copenhagen 2027
No 2027 edition or CFP posted yet. The 2026 edition (already concluded) closed its CFP 1 Feb 2026.

Clerk's scope note — NDC Sydney and other non-European NDC editions, and Microsoft 365 Community Conference (Las Vegas), are excluded — Europe-only per the brief. DotNext (historically Moscow-based) is omitted given the practical travel/visa reality for a Belgium-based speaker.
