# Time parameters

When planning a route, set the route date according to the time zone.

## Route date {#date}

To set the route date, use the `options.date` parameter in `YYYY-MM-DD` format. The parameter is important for calculating the [relative time windows](https://docs.routeq.com/doc/en/vrp/properties-of-time-window.md#relative-time-windows). If the route date is not defined by the user, then the current date is used according to the time zone.

If you plan the route via the interface, the route date is defined in the [settings](https://docs.routeq.com/doc/en/vrp/interface-import.md#step-3).

{% note info %}

If you don't pass the `options.date` parameter value, then the solution can't be viewed or edited in Routing Workspace. It can be viewed only in JSON format or [on the map](https://yandex.com/courier/mvrp-map#json).

{% endnote %}

## Time zone {#time-zone}

Relative time windows are calculated in the time zone that is set with the `options.time_zone` parameter. The `time_zone` field is mandatory.

The API has two options for specifying the time zone:

- As a number between -12 and 14 that determines the offset relative to UTC in hours. For example, 1 corresponds to GMT+1 (London).
    
- As a string. For example, `Europe/London`.    

When you plan a route in the interface, the time zone specified in the [settings](https://docs.routeq.com/doc/en/vrp/interface-import.md#step-3) is used.

Use a [list of time zones](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones) to specify the time zone.

{% note alert %}

GMT and Etc/GMT are two different ways to specify a time zone. For example, GMT+1 corresponds to Etc/GMT-1.
