Sources & Methodology
NYC Dayline combines evergreen editorial guides with current public information. The source strategy depends on what kind of claim a page is making.
Government and public-service data
For city rules, permitted events, taxes, transit fares and public services, we prefer the government department, public authority or official dataset responsible for the information. Examples include NYC agencies, NYC Open Data, MTA, the National Weather Service and relevant state authorities.
Institutional sources
Museums, parks, attractions and cultural institutions are best used for their own current operating information, ticket conditions, access rules and official visitor guidance. We do not treat promotional language as independent evidence of quality.
Frequently changing information
Weather, event listings and official announcements may be collected from public feeds or official pages. When current data is unavailable, we prefer to show that limitation instead of inventing a fallback fact.
Evergreen guides
Neighborhood, itinerary and planning guides are written around geography, tradeoffs and durable visitor decisions. Specific prices, schedules and business recommendations are included only when they can be maintained responsibly.
Recommendations
Recommendations are editorial judgments, not measurements disguised as facts. We aim to explain why something fits a particular traveler, budget, neighborhood or itinerary rather than using unexplained “best” rankings.
Links to sources
When an official source materially helps a reader verify a fare, rule, ticket condition or operating detail, we link to it directly from the relevant guide or calculator.
