About those.kr

those.kr brings everyday time, date and internet tools together in one free website. No installs and no sign-up — just open it in your browser.

Tools

• IP Lookup
• Timer
• Stopwatch
• World Clock
• Date Calculator
• Time Calculator

There are also quick-start pages for popular tasks such as a 5-minute timer, a Pomodoro timer, the current time in major cities, Christmas and New Year countdowns, and a 100-days calculator.

What we care about

• Fast and simple — the tool comes first and works well on phones.
• Runs on your device — the timer, stopwatch and date and time calculators run entirely in your browser. What you type is not stored on our server.
• No accounts — we do not ask for personal information. Only when you use the contact form do we collect the minimum needed to reply. See our Privacy Policy.
• Korean and English — every tool is available in both languages.
