Feasible Day: walkable day plans checked against opening hours

Feasible Day is a free walking itinerary planner. Pick a city, your interests and a date, and it builds a one to three day plan from real OpenStreetMap places. Every stop is checked against its opening hours on that date, every transfer is checked against walking time, and places whose hours are unknown are labelled instead of guessed.

Why it exists

AI chatbots write itineraries that read well but often send you to closed venues or to walks that do not fit the gap. In a published test of 96 days across 12 cities, Llama 3.3 70B and Llama 3.1 8B produced a fully feasible day in 2 of 576 runs. This planner passes every one of the 96 days on its own rules, and 94.8% of plans when every walk is re-timed by an independent routing engine. Method and limits are public.
