Why the Time Difference Between Two Cities Changes With the Date
New York to London is not always five hours. Daylight saving starts and ends on different dates in different places — which is why a real converter asks for the date, not just the cities.
Frequently asked questions
Are the tools really free?
Yes — basic tools are free and need no account.
Are my files uploaded?
Browser-based tools process everything on your device. Tools that need a server or AI provider say so clearly on their page.
How does the platform scale to 50,000+ tools?
Tools are database records with a registered handler in a reusable execution engine — new tools are added as data, not as new pages coded one by one. Only tools with real, tested handlers are published.
