What is DateGuess?
Key Features
One shared daily puzzle: Everyone receives the same historical event, with a new challenge at midnight UTC.
Five guesses and progressive clues: Start after the first clue; each wrong guess unlocks another, up to five clues. There is no separate reveal or skip button.
Year-distance feedback: Wrong guesses normally show how many years earlier or later to try. Within three years, “Close!” replaces the distance; an exact year is still required.
Browser progress and streaks: Revisit saved guesses and results in the same browser. Consecutive UTC-day wins build current and longest streaks; progress does not sync across devices.
Archive and result sharing: Read past clues, answers, background and source links. Copy or share a completed result, noting that its text includes the answer year.
Use Cases
- Play a short daily history challenge during a break.
- Compare reasoning with friends after everyone has finished the same puzzle.
- Use historical clues as a classroom discussion prompt.
- Read missed puzzles and follow their historical source links in the archive.
How to Use DateGuess
- 1Read the first clue in today’s puzzle. At the November 15, 2026 review, accepted guesses ran from year 1000 through 2026.
- 2Enter a year and submit a guess. Use the earlier-or-later feedback to adjust your estimate.
- 3Read the next clue after a wrong guess. “Close!” means within three years, but only the exact year wins.
- 4Solve within five guesses or read the answer after the fifth attempt. Review the background and source; share only after others have played, because results reveal the year.

FAQ
Is DateGuess free, and do I need an account or app?
The daily puzzle and archive are free, with no account or download required. It runs in a web browser. Your saved progress and streaks stay in that browser, so they do not follow you to another device.
How is my score calculated?
The score is the number of guesses used to solve the puzzle: 1/5 is the best result. X/5 means all five guesses were used without finding the exact year. “Close!” means within three years and is not a win.
Can I replay old puzzles?
No. Archive entries show all five clues, the answer, historical background and source link for reading. Only the current daily puzzle is playable. It joins the archive after its UTC day ends.
When does a new puzzle appear?
Every day at midnight UTC, which is 08:00 in Beijing. Everyone receives the same historical event. Consecutive UTC-day wins build a streak; a loss or missed UTC day breaks the current streak.
Does sharing a result reveal the answer?
Yes. The result text includes the puzzle number, score and answer year. Avoid sending it to someone who has not played yet. The site provides result copying and an X sharing link.
