What's new

27 September 2026

• DuskDial opened: bedtimes counted back from an alarm in whole sleep cycles, with the cycle length and the time to fall asleep printed on every page and yours to change.
• A page for each common alarm from 4:00 to 8:00 am and for two afternoon alarms after night shifts, each with when that alarm and its bedtimes fall in daylight and what the clock-change nights do to it.
• The travel planner, which moves a bedtime across time zones before you fly or after you land, with a page for each of 42 routes giving its January and July gap, 10 of them with a written account of how the gap moves through the year.
• Shift work: a rota planner for any run of day shifts, night shifts and days off, with 6 named patterns to start from, commute and the switch days included, and the sleep downloadable as a calendar file; and a page for each of five single shifts saying when its hours fall in daylight across the year and what the clock-change nights do to it.
• Naps, each length set against the break rules in the United Kingdom, South Africa and the United States; the sleep-now count; the week's tally; and three tools: a two-way alarm, a screen cutoff and a world clock.
• A clock-change planner for 14 March 2027 in the United States and 28 March 2027 in the United Kingdom and the European Union, and a notebook, kept on your device, that fits a cycle length from 70 to 120 minutes to your own mornings.
• A link beside each calculator that carries its settings, so a bookmark or a link you send reopens it the way you left it; a nightly calendar file from the wake pages and the bedtime alarm; and an offline copy, kept on your device only when you ask for it, so the main pages open with no connection.
• Reference pages on where the ninety minutes came from, the fifteen minutes before sleep, and what the site cannot know.
• About, contact, privacy, cookies, terms, the disclaimer and the accessibility statement.
