About ChronoFive

ChronoFive is a free daily history challenge: five carefully chosen events, five year guesses, and a short story after each round so the dates stick.

What it is

Each calendar day has a fixed lineup of five historical events. You estimate the year for each one using typed input and a scrollable era wheel. After every guess you see how close you were, then a concise reveal with context and optional Wikipedia sources. At the end you get a score summary you can share.

Why it was created

Most “history trivia” apps reward speed or obscure facts. ChronoFive is built around chronological intuition—feeling when something happened—and then rewarding curiosity with the story, not just a green checkmark. The goal is a habit people look forward to: a few quiet minutes with real events, every day.

Daily puzzle philosophy

Everyone playing on the same calendar date gets the same five events. That fairness matters for streaks, sharing, and leaderboards. Archive days use the same idea: each past date keeps its original lineup so revisiting a day is revisiting that puzzle, not a random redraw.

Who it’s for

Casual players who like Wordle-style dailies, teachers and students who want a light history warm-up, and anyone who enjoys connecting years to human stories. You do not need a history degree—curiosity and a willingness to be wrong are enough.

Archive play

You can open past puzzle dates from the ☰ menu → Archive (or Account → Calendar). Free accounts can play the last 7 days; Chrono+ unlocks the full archive. Completed days can reopen a full summary when your browser still has that day’s save. Chrono+ also unlocks practice replays on days you already finished.

Chrono+

Chrono+ is an optional subscription for players who want the full archive, one daily re-guess, streak forgiveness, ad-free play, personal Insights and Weekly Recaps, a Seen Events Timeline, Saved Stories, and custom wheel themes. The core daily puzzle remains free.

How we pick and cite events is documented on our Editorial Standards page. Questions? See Support or Contact.
