When it comes in handy
A clock on a shared office monitor
In full screen, the clock is big enough to read from across the room.
Just open this page on a spare monitor or an old tablet and press the full-screen button. The "With calendar" design also shows this month's calendar and the Japanese era year. No special software needed.
Remembering calls and appointments
Add an alarm with a time and label, and a full-screen alert appears at that time.
Add as many as you like, such as "Call back at 2 pm". For daily stand-ups or end-of-day tasks, use the "Every day" or "Weekdays" repeat. Alerts use both sound and the screen, so you will notice even with the sound off.
Timing your work
Use the stopwatch lap feature to record the time for each step and copy them all at once.
Press "Lap" at the end of each step to record the total time and the time since the previous lap. Copy the record with one click and paste it straight into a spreadsheet.
The time shown depends on the clock of your computer or smartphone. If you need the exact time, check your device's time settings. Alarms and timers only work while this page is open, and browser or power-saving settings may delay or silence alerts. Please use a reliable backup for important appointments.
