DaysGap is a small collection of date and time calculators built around one idea: answering a date question should take seconds. No sign-ups, no pop-ups, no pages that take forever to load. You pick your dates and the answer is there.
How we keep results accurate
Every calculation uses the real Gregorian calendar, including leap years and varying month lengths. Holiday rules for the US and UK follow the official published rules, including observed and substitute days. All calculations run in your browser, so your dates never leave your device.
