Status: de facto

It is possible to enter opening hours for almost everything that has known hours of operation. Supermarkets and small convenience stores close in most countries at different times (even in the same city), in metropolitan areas there are often small shops open the whole night. Some pharmacies, gas stations, pubs and fast-food-restaurants are open 24/7. This is a very important information if you are looking for a certain facility at night.

Additionally, you can tag the URL where the current opening hours can be looked up with opening_hours:url=

Please be aware of these documents before reading this page: Proposed features/Time domains and Key:opening_hours/specification.

Summary syntax

This is a summary covering most cases. Its goal is to allow writing most Opening Hours tags in a short time, not to explain the full syntax. For more complicated cases, please refer to the text below this section, to the full specification and to more explanations.

You can check your compositions with the evaluation tool, or the simpler YoHours application.

Note: Anyone being sure to have understood something upon which everyone agrees and that's different from this syntax explanation is welcome to make the correction in it.

code is either written literally as such (including a literal space separator   where needed; elsewhere spaces in the syntax are only for its presentation);
element is to be replaced by the element whose syntax is defined in a line starting by element: below;
item... means that item can be repeated as needed.
[ sequence of items ] means that the sequence of items is optional;
| indicates that one of the sequences of items (separated by this symbol) must be chosen;
General syntax
opening_hours= rulesets [ ; rulesets ]...
Each ruleset is evaluated in order, the next ruleset possibly overriding the initial open or closed state that may have been matched in the previous rulesets.
rulesets: rule [ || rule ]...
Each rule is evaluated in order until it matches for the indicated dates or times, otherwise the next rule in the ruleset will be checked only as a fallback.
rule: range [ status ] [ comment ]
range: [ years ] dates [   times ] | times | 24/7
Syntax for specifying optional years
years: year_range [ , year_range ]...
year_range: year [ - year | + ] [ / n ]
An optional period of n years may be specified for years to include within the specified range starting at the first specified year.
year: A 4-digit year number in the Gregorian calendar.
Syntax for specifying dates (with optional times)
dates: monthly | weekly | daily | variably | holidays
monthly: monthdays [   weekdays ]
weekly: [ week   week_range [ , week_range ]...   ] weekday_range [ , weekday_range ]...
daily: months [   monthdays [ , monthdays ]... ]
variably: variable_date [ - variable_date ]
months: Mth [ -Mth ]
monthdays: dd [ -dd ]
week_range: ww [ - ww | + ] [ / n ]
An optional period of n weeks may be specified for weeks to include within the specified range starting at the first specified week number ww.
weekdays: weekday_range [ , weekday_range ]... | Wd[ n [ , n ]... ]
Week days may be followed by rank numbers, counted positively from the start of the month, or negatively from the end of month:
e.g. Mo-Fr 08:00-09:00, or Mo[1,3] 08:00-09:00;
e.g. Su[1] means the first Sunday of the month, and Su[-1] means the last Sunday of the month.
weekday_range: Wd [ - Wd ]
ww: A 2-digit week number (in ISO year) in range 01-53, e.g. week 25 Mo 08:30-20:00
dd: A 2-digit monthday number in range 01-31, e.g. Dec 25
Mth: Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec
A 3-letter abbreviated English month name, e.g. Dec 25
Wd: Mo | Tu | We | Th | Fr | Sa | Su
A 2-letter abbreviated English weekday name, e.g. Fr 08:30-20:00
variable_date: yearly_fest [ sign n days ]
yearly_fest: easter
For now, the only variable yearly fest day specified is Easter (assuming the Christian Gregorian calendar).
holidays: PH | SH
Public holiday (location dependent, requires data per country/region); scholar holiday (location dependent, requires data per scholar academy).
Syntax for specifying times
times: time_range [ , time_range ]...
time_range: time [ - time | + ]
time: fixed_time | variable_time
fixed_time: HH : mm
variable_time: event | ( event offset_time )
event: dawn | sunrise | sunset | dusk
Note that sunset and sunrise times requires geolocation to compute the position angular elevation of the sun, and the the angular elevation of the observable horizon (which is also dependent of the altitude). They may be approximated at sea level on the modeling geoid, or just estimated roughly in local time (per country and time zone).
offset_time: sign hh : mm
hh: A relative 2-digit hours number in range 00-48, e.g. (sunrise+01:00)-12:00.
HH: An absolute 2-digit hours number (in day, in 24h format, no am/pm) in range 00-23, e.g. Fr 08:30-20:00.
mm: A 2-digit minutes number (in hour) in range 00-59, e.g. Fr 08:30-20:00.
Other generic syntaxic elements used for tuning dates and times
sign: + | -
n: A positive integer.
Syntax for optional modifiers
status: unknown | open | closed | off
unknown: initial open or closed state, except at overriding dates and times that follow (may also be used to override a previous explicit open or closed status);
open: open at the indicated dates and times (or permanently if no time is given), except at overriding dates and times that follow;
closed or off: closed at the indicated dates and times (or permanently if no time is given), except at overriding dates and times that follow;
In each rule of the first ruleset of the tag value (including fallbacks), if the status is not explicitly specified with the specified range, it is assumed to be meant as open, leaving all other unspecified dates and times as unknown; the resulting schedule is then successively modified by each following ruleset.
comment: "text"
A short comment (wrapped in " but not containing any " within) showing applicable restrictions or specifications, e.g. "children only", "limited service", or "reservation by phone".
This comment is intended to be displayed in applications and not to be interpreted automatically. The language used in this comment is not specified by the tag value itself, but this could be specified (for localisation purpose) by tags whose key contains a language code suffix.

How to map

This is a property tag so it must go with a related tag; e.g.,


Before tagging ways way, see Key:access.

The evaluation tool and YoHours are web tools which help to determine the values. Please use English for weekday and month names.


  • 24/7
    Applied to: any non-stop facilities (related tags), 24 hours a day, 7 days a week
    Render on map: something like object icon with a 24
  • Sa-Su 00:00-24:00
    Applied to: opens only the weekend but non-stop, 24h
  • Mo-Fr 08:30-20:00 or for more complex opening hours:
    Mo 10:00-12:00,12:30-15:00; Tu-Fr 08:00-12:00,12:30-15:00; Sa 08:00-12:00
    Mo-Su 08:00-18:00; Apr 10-15 off; Jun 08:00-14:00; Aug off; Dec 25 off
    Applied to: any facilities with opening hours (related tags)
    Render on map: nothing, info recovered by software
  • Mo-Sa 10:00-20:00; Tu off or Mo-Sa 10:00-20:00; Tu 10:00-14:00
    For exceptions in a range of days
    Applied to: any facilities with opening hours (related tags)
    Render on map: nothing, info recovered by software
  • sunrise-sunset
    Applied to: opens every day between sunrise and sunset.
    Use round brackets to add a time offset, for example a park that opens 2 hours after sunrise and closes 2 hours before sunset (sunrise+02:00)-(sunset-02:00)
  • Su 10:00+
    Sunday from 10:00 to an unknown or unspecified closing time.
    Applied to: any facilities with opening hours (related tags)
    Render on map: nothing, info recovered by software
  • week 1-53/2 Fr 09:00-12:00; week 2-52/2 We 09:00-12:00

  • Mo-Sa 08:00-13:00,14:00-17:00 || "by appointment"
    Here does the fallback rule come in handy. It applies for any time which was not handled by previous rules.
  • Su-Tu 11:00-01:00, We-Th 11:00-03:00, Fr 11:00-06:00, Sa 11:00-07:00
    Because of the definition that following rules will overwrite previous once, times which span over midnight have to use additional rules which are separated by a comma instead of a semicolon.
  • Mo-Su,PH 15:00-03:00; easter -2 days off
    Every day, even on public holiday open, but closed on good friday.


  • wd weekday, available: Mo · Tu · We · Th · Fr · Sa · Su (e.g., > Fr 08:30-20:00)
  • hh hour, always two digits number in 24h basis (no am/pm), in the format "hh:mm" · (e.g., > Fr 08:30-20:00)

  • we week number, always a two digit number in range 01-53, in the format "week we" (e.g., > week 25 Mo 08:30-20:00)
  • SH School Holiday, can be used to indicate different opening hours during school holidays (e.g., Mo-Fr 08:00-09:00,14:00-15:00; SH off)[1]
  • PH Public Holiday, can be used to indicate different opening hours during public holidays (e.g., Mo-Fr 09:00-17:00; PH 10:00-12:00; PH Su off)[1]
The above example means normal hours are Monday to Friday 9am to 5pm, except on public holidays it is 10am to 12pm, except public holidays that fall on a Sunday.

The general syntax for the value is: hh:mm-hh:mm (e.g., > 08:30-20:00).

The general syntax for the value is: wd hh:mm-hh:mm (e.g., > Fr 08:30-20:00).

The general syntax for the value is: mo md: hh:mm-hh:mm (e.g., > Dec 25: 08:30-20:00). Note that the colon is optional as mentioned under Key:opening_hours/specification.

The general syntax for the value is: mo-mo: wd hh:mm-hh:mm (e.g., Jun-Aug: Su 10:30-16:00 to specify the opening times on Sundays in June, July and August). Note that the colon is optional as mentioned under Key:opening_hours/specification.

The general syntax for the value is: week we: wd hh:mm-hh:mm (e.g., > week 25: Mo 08:30-20:00). Note that the colon is optional as mentioned under Key:opening_hours/specification.


  • Consecutive hours [always needs open-close] separated by "-" · (e.g., > 08:30-20:00)
  • Consecutive weekdays open separated by "-" · (e.g., > Mo-Fr)
  • Consecutive monthdays open separated by "-" · (e.g., > Dec 20-26) or (e.g., > Dec 20-Jan 06)
  • Open with periodicity "n" within a range of consecutive monthdays, the range is followed by "/n" (e.g., > 02-30/n)
  • Consecutive weeks open separated by "-" · (e.g., > week 01-26)
  • Open with periodicity "n" within a range of consecutive weeks, the range is followed by "/n" ( e.g.> week 02-52/n )
  • A break on days separated by "," · (e.g., > Mo,We,Fr)
  • A break on hours separated by "," · (e.g., > 08:30-14:00,16:30-20:00)
  • Different hours on different days are separated by ";" (e.g., > Mo 10:00-12:00,12:30-15:00; Tu-Fr 08:00-12:00,12:30-15:00; Sa 08:00-12:00)
reads as: this opening hours for this days ; this opening hours for this days
  • A weekday off will be tagged as "wd off" (e.g., > Tu off)
  • A range of weekdays off will be tagged as "wd-wd off" (e.g., > Tu-Th off)
  • A month off will be tagged as "mo off" (e.g., > Aug off )
  • A range of months off will be tagged as "mo-mo off" (e.g., > Aug-Sep off)
  • A monthday off will be tagged as "mo md off" (e.g., > Dec 25 off)
  • A range of monthdays off will be tagged as "mo md-md off" (e.g., > Dec 24-26 off) or "mo md - mo md off" (e.g., > Dec 25-Jan 06 off )
  • Exceptions to a range of days, first the range then the exception (e.g., > Mo-Sa 10:00-20:00; Tu off) or (e.g., > Mo-Sa 10:00-20:00; Tu 10:00-14:00) or (e.g., > Mo-Fr 08:00-12:30; We 14:00-17:00)
This means these are not additions, for example Mo-Fr 08:00-12:30; We 14:00-17:00 means that on Wednesdays, the shop is only opened in the afternoons and not additionally.
  • If it is in the first or last day of a range then don't use the exception rule, use the usual (e.g., > Mo-Fr 10:00-20:00; Sa 10:00-14:00)
  • Non-consecutive or semi-consecutive days of the week will be tagged as wd[x] (e.g., Su[3] 09:00-12:00)
This is used to indicate the 3rd Sunday of the month from 9am to 12pm.
Use -1 to indicate the last day of the month; e.g., Aug Th[-1] means last Thursday in August.
Can use grouping, (e.g., Su[1,3,5] and Su[1-3])
  • If hours are non stop some days then (e.g., > 00:00-24:00)
  • If it is 24 hours 7 days a week it has a specific value: 24/7.
This way it can render a specific icon.
  • A special time value to mark the time the sun rises is: sunrise.
  • A special time value to mark the time the sun sets is: sunset.
  • A + after a time means "from" or "open end" (e.g., Sa 22:00+ or Sa 18:00-22:00+)

See the formal specification for more details.

Non-Gregorian Calendars

There has been some discussion about how to map non-gregorian calendars ( “Opening hours syntax for non Gregorian calendar”. 17 May 2019.  ).



JavaScript implementation by User:Ypid:


OsmAnd 2.0 showing whether the POI is known to be open or closed based on tagging of opening_hours. For example, the my daBBA restaurant was closed when the screenshot was taken; however, Sugran Swayapakghar was open.

OsmAnd uses this tag on the POI search screen. The implementation is only partial, currently, no dates, week numbers, or holidays are supported but most values should get parsed.

Opening hours for Ulm, Neu-Ulm & surroundings

Ulm, Neu-Ulm and surrounding areas.

The web application is available on Opening hours for the local area are visualized on a map. The source code of this application is freely licensed and available via GitHub. Adapting the application to a different city is very easy and described on the GitHub page.

  • YoHours, a website to create opening hours simply by dragging time intervals on a calendar.



In the case of 24/7, it can be something like adding a 24 to the object icon.

The rest of values have no obvious rendering and may be accessed with the context menu or alike.

Former deprecated tags

The following (undocumented) keys have been deprecated and should be replaced by this opening_hours=*. Their value should be interpreted to set the value of the new key, as described above:

There is an alternative system for default values which is currently not evaluated by opening_hours.js: Default is a proposal for a default values system. This proposal can set default values such as maxspeed for areas (countries, states...) but also holidays periods. A country, a zone area can subscribe to a default containing such holidays definitions.
