| date | `Optional[pydantic_extra_types.pendulum_dt.Date]` | `rw` | `None` | Optional specific calendar date for the time window. Naive — matched against the local date of the datetime passed to contains(). Overrides `day_of_week` if set. |
| day_of_week | `Union[int, str, NoneType]` | `rw` | `None` | Optional day of the week restriction. Can be specified as integer (0=Monday to 6=Sunday) or localized weekday name. If None, applies every day unless `date` is set. |
| duration | `Duration` | `rw` | `required` | Duration of the time window starting from `start_time`. |
| locale | `Optional[str]` | `rw` | `None` | Locale used to parse weekday names in `day_of_week` when given as string. If not set, Pendulum's default locale is used. Examples: 'en', 'de', 'fr', etc. |
| start_time | `Time` | `rw` | `required` | Naive start time of the time window (time of day, no timezone). Interpreted in the timezone of the datetime passed to contains() or earliest_start_time(). |
| value | `Optional[float]` | `rw` | `None` | Value applicable during this time window. |

### Sequence of value time windows
This model specializes `TimeWindowSequence` to ensure that all
contained windows are instances of `ValueTimeWindow`.
It provides the full set of sequence operations (containment checks,
availability, start time calculations) for value windows.
| windows | `list[akkudoktoreos.config.configabc.ValueTimeWindow]` | `rw` | `required` | Ordered list of value time windows. Each window defines a time interval and an associated value. |

### Common configuration settings for fixed electricity pricing
This model defines a fixed electricity price schedule using a sequence
of time windows. Each window specifies a time interval and the electricity
price applicable during that interval.
