Dates, workdays, timers, world clocks, meeting planning and printable calendars in one private browser workspace.
Choose a workflow. Nothing is calculated or loaded automatically.
One actual standalone tool is active at a time. Reset, Close or switching releases its inputs, generated calendars and running timers. Clocks/timers do not continue in a hidden panel. Filters leave the active tool untouched. Save reports before switching; no dates or settings transfer automatically.
Choose a date/productivity workflow above. Plan dates, run a timer, compare clocks or make a calendar entirely on your device.
Gregorian dates, explicit weekend/holiday rules and browser-installed time-zone rules. Meeting times reject skipped local times and require an explicit repeated-time choice. Timers use the device wall clock, stay in the active page and can be delayed by sleep/background throttling. Calendar HTML is self-contained; each month starts on a new printed page. ICS exports actual supplied custom dates or UTC meeting times. Each tool retains its original supported scope and limits.
All dates, timers, time-zone calculations and custom calendars remain in the browser. One actual standalone interface is active at a time, with no hidden data sharing, uploads or input history.
Thirteen: Date Calculator, Business Days, Countdown, Stopwatch, Pomodoro, World Clock, Meeting Planner, Week Number, Leap Year, Calendar Generator, plus the existing Age, Date Difference and Time Zone tools at their original URLs.
No. Only one tool is active. Reset, Close, workflow switching or page exit releases the old panel and stops its timers/clocks. Search/group filters alone keep the current tool open. Download a session snapshot before leaving if you need a record.
No. Supply your own weekend/holiday dates. Clocks use the device clock and browser-installed zone rules. Meeting conversion reuses explicit skipped/repeated-time handling. Device clock changes and background sleep can affect timer feedback.
Yes. The workspace mounts the actual standalone interface, scripts and styles in one isolated panel. All standalone URLs remain available, with no automatic data transfer between them.
