Use TIERHOT without sign-up or installation.
Calculation conventions
Each page explains its supported inputs, formulas and limits. Calendar tools include weekends and holidays. Time tools use minute-based clock arithmetic without time-zone or daylight-saving conversion. The average calculator assigns equal weight to every number. Unit conversion displays rounded numerical results. Check the stated conventions against any separate requirements for your use.
Random selection
Random tools use browser-generated random values. Repeated results can occur across separate draws. Name picking merges identical labels, while team generation requires distinct labels. These tools do not provide identity verification, certified public drawings or tamper-proof audit records.
Personal daily numbers
The daily number combines your name, birth date and Korea date using TIERHOT's own deterministic method. Its themes are symbolic reflection prompts, not scientifically validated predictions or guarantees of future outcomes. A shared date and number are editable link parameters, not an authenticated personal report.
Lottery numbers
The generator creates combinations under Korean Lotto 6/45 rules. It does not predict winning numbers or provide lottery purchases.
Passwords and retained results
Use a separate password for each account and store it securely. Inputs and results are not stored on the site server and cannot be recovered after closing the page. Anything you copy or download may remain on your device.
