Measured tools (15)

• find_best_meeting_time read-only

  Propose up to three fair meeting times while the slot is still being chosen. Ranking does not take a meeting length. A city's public holiday down-ranks that slot and is named in the reasons. Each slot city says whether that date is a holiday. Each slot has a score and the reasons. The result has one https://timeofmeeting.com link that opens the planner with those cities, and next_step, which says the user can choose a duration when creating the invitation. It does not include calendar files or a QR code. After a slot is chosen, call create_meeting_link.

  Parameters:

  • cities (required) — array — Two to eight cities. An array, or one comma-separated string. City name or a city id from search_cities. Spelling and accents are flexible. When several cities share a name, the best match from the site search is used and the others come back in alternatives.
  • end_date — string — Last day, YYYY-MM-DD. Defaults to six days after the start. At most 31 days.
  • start_date — string — First day, YYYY-MM-DD. Defaults to today (UTC).

  Hints: read-only yes · destructive no · idempotent not declared · open-world no

  Convert one city's local time into one or more other cities. Each city says whether that local date is a public holiday. The result includes a https://timeofmeeting.com link for a 60-minute meeting. Choose a different length with create_meeting_link.

  Parameters:

  • from (required) — string — The city the clock time belongs to. City name or a city id from search_cities. Spelling and accents are flexible. When several cities share a name, the best match from the site search is used and the others come back in alternatives.

  Hints: read-only yes · destructive no · idempotent not declared · open-world no

• create_meeting_link read-only

  Build the invitation for one chosen slot. duration_minutes is the meeting length, chosen now, with the same choices as the planner Duration control. title is an optional meeting name, e.g. Weekly sync. Each city says whether that date is a public holiday. The first item is always the planner link: open this meeting on timeofmeeting.com (see and adjust it in the planner). formats then adds text to paste into a chat or email, a calendar file for Outlook, Apple Calendar and most calendar apps, an add-to-Google-Calendar link, or a QR code image someone can scan with a phone, in that order. The calendar file is https://timeofmeeting.com/c?q=. Use this after find_best_meeting_time, or when the time is already known.

  Parameters:

  • cities (required) — array — Two to eight cities. An array, or one comma-separated string. City name or a city id from search_cities. Spelling and accents are flexible. When several cities share a name, the best match from the site search is used and the others come back in alternatives.

  • formats — array — Extras after the planner link, which is always included: open this meeting on timeofmeeting.com (see and adjust it in the planner). Returned in this order: text (text to paste into a chat or email), ics (calendar file for Outlook, Apple Calendar and most calendar apps), google (add-to-Google-Calendar link), qr (QR code image someone can scan with a phone). Default when omitted: ["text", "ics", "google"]. An empty array returns the planner link only. qr is included only when requested.

• get_holidays read-only

  List public holidays for a country, an optional ISO 3166-2 region, or a city. Pass one year, a list of years so 2026, 2027, and 2028 can come back together, or a date range. Each holiday has the date, the weekday, whether it falls on Saturday or Sunday, whether it creates a long weekend of three or more days with Saturday and Sunday, the local name, the English name, whether it is regional, the region codes, the file it came from, and the calendar page URL. The same holiday list marks the planner timeline.

  Parameters:

  • city — string — Optional city. Its country and region are used. City name or a city id from search_cities. Spelling and accents are flexible. When several cities share a name, the best match from the site search is used and the others come back in alternatives.
  • year — integer — One calendar year. Defaults to the current year when years, start_date, and end_date are omitted. Do not pass year and years together.
  • years — array — Calendar years, such as [2026, 2027, 2028]. A gap is not filled in. Do not pass years with year or with a date range.
  • region — string — Optional ISO 3166-2 code, such as DE-BY or GB-SCT. National holidays are included with that region's own days.
  • country — string — ISO 3166-1 alpha-2 code or English country name. UK is accepted for the United Kingdom.
  • end_date — string — Last day, YYYY-MM-DD.
  • start_date — string — First day, YYYY-MM-DD. Use with end_date instead of year. At most 366 days.

  Hints: read-only yes · destructive no · idempotent not declared · open-world no

• days_between read-only

  Count calendar days from start to end. Both are YYYY-MM-DD. include_start and include_end default to false, so the count is the dates strictly after start and strictly before end: 2024-02-28 to 2024-03-01 is 1 in a leap year (29 February) and 0 in a common year. Set both to true to count every date from start through end (3 in that leap-year span, 2 otherwise). The count is negative when end is before start. The same day is 0 unless both ends are included, which is 1. The result is that count and nothing else.

  Parameters:

  • start (required) — string — First date, YYYY-MM-DD.
  • end (required) — string — Second date, YYYY-MM-DD.
  • include_end — boolean — Count end. Default false.
  • include_start — boolean — Count start. Default false.

  Hints: read-only yes · destructive no · idempotent not declared · open-world no

• working_days_between read-only

  Count working days from start to end for one country. A working day is Monday to Friday and not a national public holiday. Saturday and Sunday are weekends, the same rule as the planner. Regional holidays are not skipped. include_start and include_end work the same way as days_between and default to false. Holiday dates are the bundled vacanza/holidays list (MIT) for 2026, 2027, and 2028. A date outside those years returns an error naming the missing year, instead of guessing. The result lists the national holidays inside the counted span, including the local name.

  Parameters:

  • start (required) — string — First date, YYYY-MM-DD.
  • end (required) — string — Second date, YYYY-MM-DD.
  • country (required) — string — ISO 3166-1 alpha-2 code or English country name. UK is accepted for the United Kingdom.
  • include_end — boolean — Count end when it is a working day. Default false.
  • include_start — boolean — Count start when it is a working day. Default false.

  Hints: read-only yes · destructive no · idempotent not declared · open-world no

• add_days read-only

  Add a whole number of days, weeks, or working_days to a date. amount may be negative. unit weeks is seven calendar days: 3 weeks from Friday 2026-10-23 is 2026-11-13. unit working_days skips Saturday, Sunday, and that country's national public holidays, and the start date is not counted: 10 working days from Friday 2026-10-23 is 2026-11-06 when none of those weekdays is a holiday. country is required for working_days. For days and weeks it is optional and is not used in the arithmetic. The result is the landing date, its weekday, iso_week, and us_week. The request date, amount, unit, and country are not repeated. Holiday dates are the bundled vacanza/holidays list (MIT) for 2026, 2027, and 2028. A walk that leaves those years returns an error.

  Parameters:

  • date (required) — string — Start date, YYYY-MM-DD.
  • amount (required) — integer — Whole number of units to add. Negative walks backward.
  • unit (required) — string — days, weeks (7 days), or working_days.
  • country — string — Required when unit is working_days. ISO code or English country name.

  Hints: read-only yes · destructive no · idempotent not declared · open-world no

• next_occurrence read-only

  Find the next date on or after start that is the first, second, third, fourth, fifth, or last given weekday of its month. weekday is Mon, Tue, Wed, Thu, Fri, Sat, or Sun. start defaults to today (UTC). Example: start 2026-10-23, weekday Fri, occurrence last is 2026-10-30, the last Friday of October. If that month's occurrence is before start, the answer is in a later month: the first Monday on or after 2026-10-23 is 2026-11-02. A fifth weekday that the month does not have is skipped. The result is that date, its month, iso_week, and us_week. The request is not repeated.

  Parameters:

  • weekday (required) — string — Mon, Tue, Wed, Thu, Fri, Sat, or Sun.
  • occurrence (required) — string — Which of that weekday in the month. last is the final one.
  • start — string — Search from this date, inclusive. Defaults to today (UTC).

  Hints: read-only yes · destructive no · idempotent not declared · open-world no

• week_number read-only

  Return only iso_week and us_week for one YYYY-MM-DD date. The response has those two numbers and nothing else: no date, weekday, year, or link. ISO weeks start on Monday, and week 1 contains the year's first Thursday: 2026-12-31 and 2020-12-31 are iso_week 53. The US week starts on Sunday, and 1 January is week 1 of that calendar year, so 2022-01-01 is iso_week 52 and us_week 1. 2027-01-01 is iso_week 53 and us_week 1.

  Parameters:

  • date (required) — string — Calendar date, YYYY-MM-DD.

  Hints: read-only yes · destructive no · idempotent not declared · open-world no

• business_hours_overlap read-only

  Work-hour overlap for two to eight cities on one date. Uses the same overlap as the planner and find_best_meeting_time: work is 9:00–17:00 local, early or late is 7:00–9:00 and 17:00–19:00, and other hours are night. The result is that day's fair slot, with label best, fairest, or a shifted least-bad window, each city's local start and end, and the score. A public holiday in a city is named and lowers the score. date is YYYY-MM-DD.

  Parameters:

  • cities (required) — array — Two to eight cities. An array, or one comma-separated string. City name or a city id from search_cities. Spelling and accents are flexible. When several cities share a name, the best match from the site search is used and the others come back in alternatives.
  • date (required) — string — The day to measure, YYYY-MM-DD.

  Hints: read-only yes · destructive no · idempotent not declared · open-world no

• dst_check read-only

  Say when a city's clocks next change, and whether a planned local time falls in the spring gap or the autumn overlap. from and to bound the search, YYYY-MM-DD. Pass both or neither. When omitted, the window is today (UTC) through 365 days later. The next change is the first offset change in that window, the same list get_dst_changes uses. weeks is iso_week and us_week of that next change, or null when the window has none. The change object and a planned time do not repeat the week numbers. planned_time is a local wall time, YYYY-MM-DD HH:MM, in that city. status is unique when that clock time happens once, gap when the clocks skip it (spring forward, including the southern hemisphere), or overlap when it happens twice (clocks go back). shifted is true for a gap or an overlap. utc is the compatible resolution: the later side of a gap and the earlier side of an overlap. Do not treat utc as the only reading when shifted is true.

  Parameters:

  • city (required) — string — City name or a city id from search_cities. Spelling and accents are flexible. When several cities share a name, the best match from the site search is used and the others come back in alternatives.
  • to — string — Last day of the search, YYYY-MM-DD.
  • from — string — First day of the search, YYYY-MM-DD. Pass with to, or omit both.
  • planned_time — string — Local wall time in the city, YYYY-MM-DD HH:MM or YYYY-MM-DDTHH:MM.

  Hints: read-only yes · destructive no · idempotent not declared · open-world no

• age_duration read-only

  Age from start to end as calendar years, months, and days. end defaults to today (UTC). A birthday on 29 February does not become a whole year on 28 February of a common year: 2020-02-29 to 2021-02-28 is 0 years, 11 months, and 30 days. 2020-02-29 to 2024-02-29 is 4 years. The parts are negative when end is before start. total_days is the signed number of calendar days from start to end. The result is years, months, days, and total_days. The dates are not repeated.

  Parameters:

  • start (required) — string — Start date, such as a birthdate, YYYY-MM-DD.
  • end — string — End date, YYYY-MM-DD. Defaults to today (UTC).
