How to use the online timer
Settled into a West End matinee and simply waiting for the final curtain, you can let a countdown of two hours and twelve minutes run while your attention stays on the stage. The interval sits naturally inside that span, so there is no need to pause the clock when the house lights rise or the audience moves into the foyer.
Watching the performance means the countdown tab may spend nearly the whole show in the background. A laptop browser can reduce activity in an inactive tab, although a clock-based countdown should correct its display when you return to it. The ending sound or notification may still depend on browser permissions, power-saving settings and whether the device has gone to sleep during the matinee.
Sitting through the show without checking the remaining time makes the choice of device mainly practical. A phone can stay with you through the interval and is less likely to sleep as deeply, but it should remain silent in the auditorium; a laptop may be easier to leave open, yet closing its lid can suspend the page. For this length of performance, either device works more predictably when kept powered and awake.
Common questions
Why might a West End matinee finish later than this countdown?
The curtain may rise late, the interval may run long, or applause may extend the performance. If the countdown ends first, keep the device silent and wait for the house lights.
What if the matinee ends before the countdown does?
Running times can vary when an interval is shortened or the production has a brisker performance. Stop the remaining countdown after leaving the auditorium, where checking the screen will not disturb anyone.
