A clock press is what this chess clock counts as a move: pressing it stops your time, starts the opponent's, credits you with the configured Fischer increment, and writes one unit to a device-local daily tally you can reopen any time after the game. To check the result after using a chess clock, look at three things — the side still counting down, the value on each clock when play stopped, and the press count stored for today's calendar day. The tool does not assign a chess result, declare a checkmate, or call a flag for you; it gives you the timing record and leaves game adjudication to the players, the event, or the position on the board. Reviewing that record is immediate because every press has already been counted and every snapshot has already been saved locally. If you made a mistake, undo restores the snapshot before the bad press. If you want a copy, export turns the same local data into a PNG or CSV file inside your browser. Everything you need to confirm the timing half of the result is on one screen.
What the Result Includes on This Clock
After a game ends, the Chess Clock lets you check three specific pieces of the result without leaving the page: the two remaining times, the side that flagged if any, and the number of presses recorded for the local calendar day. The board position, the move list, the checkmate, and any rule-based decision live outside this tool. What stays here is the timing record — every press that switched the active side, every snapshot that Pause or the browser stored, and every undo that rewound one of those snapshots.
The time control you set before the first move is part of the result too. The two-column display retains the seconds you started with, the Fischer increment you applied, and an anchor timestamp from the last completed press. Together these three values — initial seconds, increment, and anchor — are enough to reconstruct what each side had when the game ended, even after you close the tab and reopen it later in the same browser.
Reading the Two-Sided Display After the Game
The large two-column display is the first place to look when checking the result. One number is for White, one for Black, and both stay visible the entire game — you do not have to remember who pressed last or do any mental arithmetic about the increment. When you stop playing, the columns show the two remaining times exactly as they were when the most recent event happened: a finished press, an undo, a pause, or a flag.
If both columns still show positive values, neither side ran out of time during this game and the timing half of the result is unfinished — something else ended it, such as a checkmate, a resignation, or a draw agreement. If one column shows 00:00, the tool has flagged that side and stopped accepting new clock presses for the current time control. A flagged clock is the clock's way of saying the timing result was a loss-on-time for the flagged player. Per the FIDE Laws of Chess, a clock press stops the player who moved and starts the opponent, which is why the side that flagged is the side whose time ran out rather than the side whose button was last.
The increment does not change how you read the display after the game. Fischer increment was added to the side that completed the press, not to the side now thinking. The starting display already included the increment, so the number at the end of the game is the number remaining after every credited increment, not before.
How to Check the Result After Using the Chess Clock
- Open the Chess Clock in your browser and let it load the saved time control and press history for today from local storage. The initial seconds and Fischer increment are restored from the most recent snapshot.
- Glance at the two remaining times. The side whose clock still shows a positive number did not run out. The side whose clock sits at 00:00 was flagged by the clock and the tool is no longer accepting new presses for this game.
- Open the daily press history panel and read the count for today's calendar day. That number equals the total completed clock presses recorded across every practice session played today in this browser.
- Compare today's count with yesterday's entry in the recent-days list to confirm the total makes sense for your session length and move tempo before exporting.
- If a press was accidental, tap Undo last press once. The full prior snapshot returns, the daily press count drops by one, and you can re-read the two clocks to confirm the result is now what you expected.
- If you need both clocks frozen at their current values before closing the tab, press Pause. Pause materializes the running time on whichever side was active and leaves both sides stopped.
- Export only when you actually need a private copy. The PNG shows the daily total and recent days on a 1080 by 1350 image. The CSV writes one row per saved day with Date and Completed clock presses for a spreadsheet or archive.
What Each Clock Event Changes in the Result
The result is the sum of every event the clock has observed during the session. Reading the table below makes it obvious which control affects which part of the record when you go back to check.
| Event in the game | What changes in the recorded result |
|---|---|
| Clock press after a move | Switches the active side, credits the increment to the pressing side, adds 1 to today's press count |
| Pause | Materializes the currently running time, stops both clocks, no press counted |
| Undo last press | Restores prior snapshot (both timers, active side, flag state, anchor), subtracts 1 from today's press count |
| Side reaches 00:00 | That side is flagged; new presses are blocked until a new time control is set |
| Set a new time control | Clears both timers and the flag state; today's press count is preserved separately |
The daily press count is the only value that persists across multiple games in the same day. Timers, active side, and flag state all reset when you start a fresh time control within the same browser session.
Reviewing the Daily Press History Day by Day
The calendar-day history is the part of the result that survives between sessions. Every completed press writes one count to the local day it happened on, and the panel lists each recent day with its count. After the timer zeros and the active side resets for the next game, the prior day's number is still there to read.
Reading the history is not the same as reading a move record — there is no notation, no piece names, and no move number. The history tells you how many clock presses happened on a given local calendar day, not which player pressed and not what the position was. That is exactly the data you need to answer the question "how many moves did I time today" without reconstructing the session by hand from a generic tally.
Each day's count is keyed to the device-local calendar. If you move clocks to a different device, that device begins empty. If you clear browser data, the saved record is removed with it. If browser storage is unavailable, the clock still runs for the current page session and the page surfaces a notice that it cannot retain history.
Exporting a Private PNG or CSV of the Record
Export exists so you can take your own copy of the daily press counts without uploading anything. The press count you can see on screen is the same number the export will contain, and that count is what the clock itself generated from each press observed during play.
Export PNG builds a 1080 by 1350 image that shows the private daily total and recent days. It contains no URL bar, no player identity, and no account — the file is drawn entirely from the local snapshot using native browser canvas APIs. Export CSV produces a file with one row per saved day, two columns labeled Date and Completed clock presses, ready to open in any spreadsheet. Both formats land directly in your downloads and never touch a server.
Export only when you actually want to keep a copy. There is no automatic upload, no cloud sync, and no scoring service behind either button. The export is a snapshot of what the clock currently remembers, not a complete match record.
What an Undo Does to the Recorded Result
Undo last press is the safety net for the recorded result. When you tap it once, the tool restores the full prior snapshot: white time, black time, the active side, the flag state, and the elapsed-time anchor all return to the values they had before the bad press. The corresponding entry is also removed from the day's press count, so the history you read after the undo is the history of the game minus the accidental tap.
This is the reason the tool keeps full snapshots instead of adjusting one number at a time. A generic minus button cannot know which side was active when the bad press happened, how much increment belonged to that press, or how the elapsed-time anchor shifted. Restoring the whole snapshot is a safer way to roll back one mistake than rebalancing separate counters, and it lets you re-read the result with confidence that the undo did not leave a stale increment behind.
Undo only rewinds the most recent press. If you have completed several moves since the mistake, undo only reverses the latest one. Repeating undo works backwards through the press history one move at a time.
What This Practice Clock Does Not Tell You About the Game
The boundary is intentional. This is a personal local practice clock, not FIDE-certified hardware, a tournament record, a game result service, a chessboard, a move recorder, or an arbiter workflow. The tool does not record which side won, whether the final position was checkmate or stalemate, who agreed to a draw, whether a flag fall was claimed under a specific rule, or which color played which opening. Tournament rules, time controls, clock certification, flag claims, and corrections are controlled by the event.
It is also a strictly local device. The snapshot lives under this tool's local browser key on this browser profile. No account, no upload, no cloud synchronization, and no remote chess server is part of the system. That is the trade for the clean two-sided timing model: everything the clock knows is on your device, and another device begins empty until you replay a game there.
