Chess Timer Features
The Chess Timer default settings makes it easy for beginning chess players to use the timer right away. Expert chess players can invoke World Chess Federation FIDE timing features including sudden death, overtime, Bronstein delays, and Fischer delays. Settings can be optimized for 'blitz' or 'long' chess matches, by adjusting time limits, and hiding or showing the seconds. Learn about its accuracy.
Use mouse or keyboard keys to run Chess Timer. Copy paste match move time
data into Excel or Word.
The Chess Timer is designed to time a chess match when playing chess face-to-face, exactly like a mechanical or digital chess clock would. It records the time of each player's moves, but does not record what piece is moved. The timer shows the player's name, current time, and optionally the move count and average move time. While the timer is running you can show and adjust the Display Settings and view the Match Data below the time display. You can view and adjust the Timing Controls when the Chess Timer is stopped. The main display looks like...
The current player's time is shown in color (user selectable), the other player's time in gray. The current player's time can be displayed larger, as shown above.
The three buttons are the heart of the Chess Timer. Each button can be selected by mouse, touch screen, or keyboard key. The keyboard key for a button is shown below the button. The Spacebar makes a good Switch key as it is the largest key and is easily accessible by both players.
Start / Pause / Resume -- Controls the flow of the timer.
Switch -- Switches timing from one player to the other.
End / Reset -- Ends match, and Resets timer for next match.
Under the buttons are links to panels for Timing Controls, Display Settings, Match Data and applying Penalties. Click the link to display show or hide the panel.
White vs Black
The Chess Timer makes no reference to white or back pieces. Instead the sides are labeled Player 1 and Player 2, or the player names you have entered. Traditionally the player
with the white pieces starts. You can use the Switch button to select whether player 1 or 2 starts, thus insuring the white side is the starting player.
The timing controls set the timing aspects of the chess match. Click 'Timing Controls' link to show or hide them. These controls are automatically saved in Cookies for you. Panel looks like...
The timing controls are independent and can be used in combinations. The 'Moves' and 'Give Odds' timing controls are ignored if there is no 'Time Limit' set for the game. To disable a timing control, leave its field blank or zero. Leaving the 'Time Limit' field blank, will cause the timer to count up from zero, thus allowing for a match with no time limit (up to 100 hours).
With the Time Delay you can not gain time. For example, if you have a 5 second Time Delay, and you move in 3 seconds, your move time will be recorded as 0 seconds. If you move in 7 seconds, your move time will be recorded as 2 seconds.
With the Time Increment you can gain time. For example, if you have a 10 second Time Increment, and you move in 6 seconds, your move time will be recorded as -4 seconds (6 - 10), thus effectively giving you an extra 4 seconds in match time. If you move in 12 seconds, your move time will be recorded as 2 seconds, and not the 12 seconds you spent during your move.

Player move times are recorded while the timer is timing. At any time you can view the move time history. When you start a new match, or refresh the Chess Timer window, the move time history is cleared out.
Under the Match Data you can select to show
the time remaining after each move, the time accumulated, or the move time itself. The Time Format field lets you select different time formats. The time values are rounded.
The penalty section lets the Chief Arbiter inflict penalties on players, by adding to a player's used or unused time. Click 'Penalty' link to show and hide penalty panel. A penalty can only be inflicted on a player during a match, not before or after a match. If you click 'Penalty' when a match is running, the match will be automatically paused for the players. Click the 'Resume' button to continue the match. The panel looks like...
Since you can affect both the used and unused time of each player, you can inflict a penalty two ways. First, by giving a time bonus to the opposing side (i.e. increasing their unused time), or by taking playing time away from the faulty player (i.e. by increasing the time of their most recent move, their used time).
If you are playing a match with no time limit, (i.e. a match that counts up from 0), then
penalties can only be inflicted on the used time, since there is no unused time in that type of match.
Our Chess Timer has our highest level of accuracy (Level 3). With each tick, the timer checks itself and makes adjustments as needed. But with that said, the accuracy and limitations of each computer will affect the accuracy of the Chess Timer.
In our tests, we found the Mac / Safari browser timing to be the most accurate, up to 1/100th of a second, and Windows PC's at 1/10th of a second. Since the chess timer only shows time to the second, or 1/10th of a second, both were fast enough for accurate timing.
Most computer's internal clocks are relatively accurate, but they can drift a few seconds a day, and we have no control over this. It is up to you ascertain the accuracy and precision of your computer's parts and our Chess Timer on your PC. In the event your computer is accurate to your satisfaction, we still do not guarantee that our timer will be accurate, or that our code is bug free or virus free.
