A single moment

Set the time first, invite guests second.

Example: October 24, 2026, 12:00 PM in Mexico City → 1:00 PM in Bogotá and 8:00 PM in Madrid.

Oct 24, 2026 · 12:00 PM Mexico City

Bogotá 1:00 PM · Madrid 8:00 PM

Event name Location or link, optional Event date Time at reference location Reference location time zone Actual duration, in minutes If the clock repeats this hour Display format

Locations and preferred windows 1 to 12 locations

Use cities or group names. Times reflect your preferred windows, not confirmed availability. A window from 22:00 to 02:00 ends the following day; the selected days indicate when it starts.

Notes for your summary, optional

Find a time that works

Try multiple days with the same windows. The range limits the start time in the reference zone; if the start of the range is later than the end, it spans overnight.

One single event, three local times

Save or share your plan

The calendar is a file to import: it does not send invitations. The settings link includes dates, zones, and windows; it excludes names, notes, and the private location or link.

Open a JSON project

Open “Find a time that works” to compare other options.

Current clocks, for reference only

These clocks display your device's current moment, not the future date of the event.

Everything is calculated on this page. We do not access accounts or calendars, and we do not store your data automatically. Files and text only leave the page when you choose to export or copy them.

How to use the planner

Choose the date, time, and time zone where you are setting the event. Use a specific city: an abbreviation like “CST” can be ambiguous.
Add the locations of the participants and their preferred windows. For a family call, you can extend into the evening or include the weekend; you don't have to stick to office hours.
Calculate the table and check the date on each row. If you're looking for another option, set the range and test up to 14 days. The “Use this time” button applies that moment to the main table.
Confirm the result with attendees and save the ICS file or the summary sheet. The calendar app that imports the ICS will display that moment in its own time zone.

An example with Mexico, Colombia, and Spain

On October 24, 2026, an event at 12:00 in America/Mexico_City starts at 18:00 UTC. In Bogotá it is 13:00, and in Madrid it is 20:00. If it lasts 60 minutes, it ends at 13:00, 14:00, and 21:00, respectively. Don't simply change the city name: recalculate whenever you change the date.

A window from 09:00 to 17:00 does not fully accommodate a 30-minute event starting at 16:45. The result will indicate 15 minutes outside the window. A window from 22:00 to 02:00 can indeed include an event that ends the following day, as long as it starts on one of the days you selected.

Method, sources, and review date

We calculate UTC timestamps and consult each zone's rules using the browser's Intl.DateTimeFormat . When converting an entered time, we look for timestamps that yield that exact local date and time. If none exists, we reject the time; if more than one exists, we prompt you to choose. Duration is added to the UTC timestamp to preserve actual elapsed minutes even if the clock shifts during the event.

The search evaluates every minute of the interval against the days and windows of each location. It ranks options first by the number of locations that fit the full event; next, by the fewest total minutes falling outside preferences; if tied, it shows the earliest UTC timestamp first. The result does not account for holidays, travel, breaks, or personal calendars.

MDN: dates, times, and time zones with Intl.DateTimeFormat.
IANA: time zone identifiers and updates.
RFC 5545: iCalendar format. The file uses DTSTART and DTEND in UTC, escaped text, and folded lines.

Method reviewed on October 23, 2026. Time rules are those installed in your browser; if local policy changes them, update your browser and re-verify the event closer to the date.

What it solves and what you should confirm

Designed for meetings, family gatherings, hybrid celebrations, and distributed teams. Supports up to 12 locations, events from 1 to 720 minutes, and searches from 1 to 14 days between the years 2000 and 2100. Labels can be city names or group names; you don't need to enter guest data.

The planner does not book a room, does not send messages, and does not know who can attend. The ICS represents a single, non-recurring event. For a recurring series, verify each date individually: clock changes can alter the time differences between countries. The PDF provides a visual summary; the CSV exports values as text; and the JSON lets you resume your settings.

Frequently asked questions

Does it take daylight saving time into account?

Yes, it uses the zone rules for the chosen date. It does not apply a fixed difference year-round. The result depends on the data installed in your browser, so it's best to keep it updated.

What happens if a time does not exist or repeats?

A nonexistent time is rejected without shifting it automatically. If the clock repeats a time, select the first or last occurrence; each option displays its UTC offset and exact timestamp.

Why does the event appear on the following day in another location?

Because a single point in time can fall across different local calendar dates. Check the complete start and end dates on each row, in addition to the time.

Why isn't there a time that works for everyone?

The windows might not overlap, or the duration might not fit completely. The search displays how many locations align and how many minutes fall outside the windows. Adjust preferences directly with attendees; the tool does not make decisions for them.

Does the ICS file send an invitation?

No. It is a local file you can import into your calendar. It contains no recipients and sends no emails. Confirm separately who will attend and how they will receive the invite.

How do I save the plan without sharing my notes?

Save the JSON project to resume it yourself later. If you only want to share the configuration, use “Copy settings without names”: that link excludes names, notes, and the private location or link, while preserving dates, zones, and windows.
