Frequently Asked Questions
How far back does the data go?
Star maps and moon phases work for any date. Weather data goes back to 1940 via the Open-Meteo historical archive. Billboard #1 songs cover 1958 onwards. President and population data covers modern history.
Is the weather data accurate?
Weather data comes from the ERA5 reanalysis dataset via Open-Meteo, the same data used by climate researchers. It uses satellite, radar, and station data to reconstruct historical weather at 25km resolution.
Do you store my birth data?
No. Everything runs in your browser. The only external call is to fetch weather data from Open-Meteo's public API. We never see or store your personal information.
