Clocks, timers and time tools for every screen
Turn any screen into a clock you can read from across the room. Choose a clean Digital Clock, a classic Analogue Clock with a sweeping second hand, or a retro Flip Clock or Nixie Tube Clock. For something more unusual, try the Word Clock, which spells out the time, the Binary Clock, or Decimal Time and Swatch .beats. Most go fullscreen with one click, ideal for a spare monitor, a classroom projector or a shop counter.
When you need to time something, the Stopwatch records laps and highlights your fastest and slowest. The Countdown Ring Timer and Hourglass Timer show time running out at a glance, great for meetings and lessons. The Pomodoro Timer alternates 25-minute focus sessions with short breaks. Every timer works from the real clock, so it stays accurate in a background tab and shows the time left in the tab's title.
For working across time zones, the Multi-City Clock Wall shows live times in the cities you choose and how far ahead or behind each one is. The Time Zone Converter handles summer time automatically for any date. Need to total up a shift? The Elapsed Time Calculator takes off breaks and gives decimal hours for timesheets. For curious minds, the Sundial Simulator shows what a real sundial in your garden reads right now, and the Clock Hand Angle Calculator solves the classic maths puzzle.
Questions and answers
- Which clock is best on a second monitor or projector?
- The Digital and Flip clocks are easiest to read from a distance, especially in fullscreen, where they fill the screen. The Analogue Clock suits classrooms where children are learning to tell the time, and the Word Clock is a calmer choice for a living room or reception desk because it only changes every five minutes. Every clock uses your device's own time and time zone, so make sure the device clock is set automatically.
- What's the difference between the Countdown Ring Timer, the Hourglass and the Pomodoro Timer?
- All three count down, but for different jobs. The Countdown Ring Timer takes any length, from seconds to hours, and drains a ring so a room can see how much time is left. The Hourglass is the friendlier, more visual option for children, with presets in minutes. The Pomodoro Timer runs a whole work routine, switching between 25-minute focus sessions and 5-minute breaks, with a longer break after every four, and counting how many you've completed.
- Should I use the Multi-City Clock Wall or the Time Zone Converter?
- Use the Clock Wall to see what time it is right now in several places at once, for example to check whether a colleague in Singapore is still at work. Use the Time Zone Converter to plan ahead: put in a future date and time and it tells you the local time elsewhere, applying each country's summer time rules for that date. That's important in March and October, when the UK, Europe and the US change their clocks on different weekends.
- Why doesn't the Sundial Simulator match my clock?
- Because a real sundial wouldn't either. A sundial shows solar time, which differs from clock time in three ways. In summer the clocks are an hour ahead of the sun. Your longitude shifts solar noon: it's about 16 minutes later in Plymouth than in London. And the equation of time makes the sun run up to 16 minutes fast or slow over the year. The simulator works out all three and shows the difference for your location.
- What are decimal time and Swatch .beats?
- They're two attempts to replace hours and minutes with something tidier. Decimal time, briefly official in revolutionary France in the 1790s, splits the day into 10 hours of 100 minutes of 100 seconds, so midday is 5:00:00. Swatch Internet Time, launched in 1998, divides the day into 1,000 .beats based on Swiss time with no time zones, so @500 is the same moment everywhere. Neither caught on, but both clocks show them live.
