More about this tool

How it works

Counts down to a date and time in any IANA time zone: days, hours, minutes and seconds left, calendar days and working days before the event day (weekends of your choice and public holidays of 16 countries skipped), daylight-saving changes on the way, the same moment on other clocks, and an .ics calendar event. The “New Year in every time zone” mode lists when midnight arrives from Kiritimati to Baker Island. The Focus Room app shows the same countdown full screen.

  • Time zones come from the IANA time-zone database through the platform’s Intl implementation. The event’s wall-clock time is converted to an instant by trying the zone’s offsets around it: a time that does not exist (the hour skipped when clocks go forward) moves forward by the gap, a time that happens twice (clocks go back) takes the earlier one; both cases are reported.
  • Remaining time is the exact difference between the two instants, split into days of 24 hours, hours, minutes and seconds. Calendar days count from today’s date in the event zone to the event day.
  • Working days count the dates from today (inclusive) up to the event day (exclusive) that are neither a chosen weekend day nor a public holiday of the chosen country (nationwide, or of the given region). Holiday data: RuleDate’s Nager.Date set for 2024–2030.
  • New Year mode: for every time zone in the built-in list (each distinct UTC offset in use, from UTC+14 to UTC−12) the instant of local midnight on 1 January is computed and zones that share it are grouped.
  • The .ics file follows RFC 5545 with the start in UTC, so calendar apps show it at the correct local time anywhere; UID and DTSTAMP are derived from the event, so the same input gives the same file.

Time-zone rules change from time to time; far-future countdowns follow today’s rules. Check holidays that matter (company closures, bridge days) yourself.

How to use the Focus Room Countdown

Count down to a moment in any time zone, see the working days left without weekends and public holidays, and get a calendar file.

What it is for

A countdown sounds simple until the event is in another time zone, the clocks change on the way, or you need to know how many working days are left rather than calendar days. This tool takes a date and time in the event's own time zone, counts from now (or from a moment you choose) and gives you days, hours, minutes and seconds, plus calendar days and working days before the event day. Weekends can be Saturday and Sunday, Friday and Saturday, Sunday only or none, and public holidays of 16 countries can be skipped.

It also shows the same moment on other clocks, writes an .ics event you can import into any calendar, and has a "New Year in every time zone" mode.

It does not know your company holidays, bridge days or school holidays — only public holidays from the bundled data (2024–2030).

Worked example

A conference starts on 2027-05-20 at 09:00 in Europe/Berlin. Counting from 2027-04-01 09:00, with Germany as the holiday country and Chicago and Singapore as other time zones, the tool answers:

  • 49 days, 0 hours, 0 minutes and 0 seconds left — 49 calendar days, 33 of them working days.
  • The event is at 2027-05-20T07:00:00Z in UTC.
  • Two public holidays fall on weekdays in that period and were skipped: Christi Himmelfahrt (6 May) and Pfingstmontag (17 May).
  • The same moment is 02:00 on Thursday in Chicago (UTC−05:00) and 15:00 in Singapore (UTC+08:00).

Why 33? From 1 April to 19 May there are 49 days, 14 of them on weekends, which leaves 35 weekdays; minus the two holidays gives 33. Today counts, the event day does not.

How to read the result

  • Days, Hours, Minutes, Seconds are the exact difference between the two moments; a day is 24 hours.
  • Calendar days count dates from today (in the event's zone) to the event day. Working days remove your weekend days and the listed holidays.
  • Event in UTC is the instant the countdown aims at — useful when you compare with other tools.
  • The holiday table lists only holidays that removed a working day; a holiday on a Saturday does not appear.
  • Warnings tell you when the zone changes to or from daylight saving time on the way, when a time does not exist (the hour skipped in spring) or happens twice (autumn), and when the period leaves the holiday data range.

Tips and common mistakes

  • Enter the time in the event's time zone, not in yours. Use IANA names such as Europe/Berlin or America/New_York; "CET" or "EST" are not accepted because they do not follow daylight saving.
  • Leave Count from empty for "now". The result then changes every minute, so use a fixed moment when you want to share numbers.
  • For regional holidays add the region code, e.g. DE-BY for Bavaria or US-CA for California.
  • The reminder goes into the calendar file only; the calendar app shows it.
  • In New Year mode the target is midnight on 1 January after the start date, in the zone you entered; the table lists every zone.

FAQ

Does the countdown handle daylight saving time?

Yes. Both moments are turned into exact instants with the time-zone rules, so a countdown across the spring change is one hour shorter in real time than the wall clock suggests, and the tool says so.

Why is the event day not a working day?

The count answers "how many working days do I still have before the event". If you need the event day included, add one when it is a working day.

Which countries have holidays?

Austria, Australia, Belgium, Canada, Switzerland, Germany, Denmark, Spain, France, United Kingdom, Ireland, Italy, Netherlands, Poland, Sweden and the United States, for 2024 to 2030.

Can I show the countdown on a TV?

Yes: open Focus Room, choose Countdown in the Display tab and press Full screen. The screen stays awake while it is shown.
