What is Everyday Tools

Everyday Tools is a free set of utilities that help you handle the small calculations and draws of daily life quickly and accurately. Whether you need to check your age, count working days, split a group bill or set an order with a ladder draw, you can use everything right in your browser with no sign-up.

Our principles (E-E-A-T)

• Experience — we reflect real-life situations (checking age, settling a group bill, planning dates) and present clear results.
• Expertise — date and time math uses UTC and Intl time zones, and randomness uses the cryptographic random generator (crypto) for accuracy and fairness.
• Authoritativeness — for policy topics such as the Korean age reform, we base guidance on official sources.
• Trustworthiness — we do not hide how things are calculated, and we do not collect or store your input.

Our tools

• Korean Age Calculator — international age and Chinese zodiac from a birth date and reference date
• Business Day Counter — working days between two dates, excluding weekends and holidays
• Ladder Game — a random ladder draw with a canvas animation
• Lottery Number Generator — 6 numbers from 1-45 with secure randomness
• Chinese Zodiac & Star Sign — the 12 Chinese zodiac animals and 12 star signs
• Bill Splitter — even and extras-based per-person settlement
• World Clock & Time Difference — current time and time difference between major cities

A note on accuracy

Everyday Tools results are for reference, based on your input and the methods we describe. The Chinese zodiac uses the Gregorian birth year, so people born before Lunar New Year may differ; lottery numbers do not guarantee a win; and for ages or dates with legal effect, always confirm against official sources first.
