About Daytool

Everyday tools that work right in your browser

Daytool is a collection of calculators and converters for life and work in Korea — pay, dates, units, tax, images and more. There are 36 tools today, and we add one more almost every day.

Principles

• Runs on your device. Numbers, text and images you add are processed in your browser only. Nothing is sent to a server or stored.
• Five languages. Every tool is available in Korean, English, Japanese, Simplified Chinese and Vietnamese, so people from abroad who live and work in Korea get the same information.
• Sources and dates. Tools based on laws or official rates show the legal basis and the date we last checked.

How we keep things accurate

Values that change over time, such as the minimum wage or tax rates, are on a review schedule and checked against official sources daily, monthly or yearly. When something changes, we update the tool and its date. Results are still for reference only; confirm important decisions with the relevant authority or a professional.

Found a mistake?

Please tell us at support@daytool.net. Mention the tool and the values you entered so we can check quickly.
