Where the answers come from
Entry rules use the open Passport Index dataset by Ilya Ilyankou (MIT), last updated 18 February 2026. Best months and plug types are curated by hand in the Explo app. Weather and public holidays on the country pages come live from Open-Meteo and Nager.Date. The Schengen calculator and the date checks run on your device, so your dates are never sent anywhere.
None of this replaces the official source. Governments change rules without notice, so check the embassy or immigration site before you book.
Keep every country on one map
Explo is a free app: light up the countries you have visited, save the ones you dream about, and check visa rules, weather and holidays before you go.
