Time & Date Tools
Frequently asked questions
Do these tools work offline?
Yes, after the page loads, most tools continue to work offline because everything runs in your browser.
Do you upload my dates or timestamps?
No. All calculations happen locally. Nothing is sent to a server.
Why do I see different results for local vs UTC?
Local time uses your device's timezone and daylight saving rules. UTC is timezone-neutral. Both are shown where helpful.
