About Hora
Hora is a small iOS app that draws your life as a grid of weeks. The site is the long-form version: essays on time, weeks, goals, and the honest math of a finite life.
Why this exists
Most productivity tools sell the fantasy that with one more system, you'll finally fit it all in. Hora is built on the opposite premise — you have a finite number of weeks, the number is smaller than you think, and what's worth doing is choosing a small handful of them on purpose.
Who writes here
Hora is built and written by Mark Frost. Background: software, design, and a long-running interest in how people actually spend the time they say matters to them. The essays on this site are first-person work, not AI-generated content marketing.
How the numbers are decided
Every figure on this site (weeks in a life, summers with a kid, weekends ahead) is either a direct multiplication or a clearly stated rough estimate. Where a number comes from a book or essay — Burkeman's Four Thousand Weeks, Tim Urban's Your Life in Weeks, Seneca's On the Shortness of Life — we link to the source and keep our math separate from theirs.
Life-expectancy reference numbers default to 80 years (≈ 4,160 weeks) because that's a round, widely-cited figure for wealthy-country averages. Any specific page may use a different reference where it makes sense (77 for Burkeman, 90 for Tim Urban). We say which one and why on the page.

Editorial principles
- Math first, feelings second. Every page that quotes a number shows where it comes from.
- No anxiety-bait. If a piece could be read as "you should feel worse about your life," it's been rewritten.
- Sources linked, not paraphrased into vagueness. When someone else wrote the line first, we name them.
- Updates are dated. If a post changes meaningfully, you'll see an "updated" date and a short note.
