Terms of use

K-ALL is a free calculator site run by Heysep, an independent operator. The English pages offer game and date calculators; the Korean pages also cover Korean pay, savings and date questions.

Calculations run in your browser. What is stored and what is not is set out in the privacy policy, and how the numbers are produced is on the about page.

Not professional advice

Results and explanations are estimates for reference, with no legal effect. They do not replace advice from a lawyer, accountant or other professional about your situation.

Check what matters

For deadlines, contracts, eligibility or anything with consequences, confirm with the organisation responsible (an employer, a court, an agency) before you rely on a date or number.

Values have a date

Game settings and holiday schedules change. Each page shows the date its values were checked and links the sources; treat anything marked unconfirmed as unconfirmed.

K-ALL is not a government body and is not affiliated with any game publisher, sports organisation or public agency.

The text, tables, images and calculator layouts on this site belong to the K-ALL operator. Quoting a short part with a credit (K-ALL and the page address) is fine. Please do not copy the whole or a substantial part, or republish a modified version, without permission.

Laws, official schedules and other public documents quoted on a page remain subject to their own terms; each page links the original.

Game names and trademarks belong to their owners and are used only to identify the games.

The English pages carry no ads or affiliate links. Some Korean pages do, and they are labelled where they appear.

Sites you reach through an outside link have their own terms and policies.

If these terms change, this page and the date below change with them.
