A timeStep that defines a pattern of dates in a year. This pattern will be repeated every year.

Each date in the year can have a different aggregation period (season).

The start of the aggregation period is exclusive and the end of the aggregation period is inclusive.

This yearlyTimeStep is meant for seasons, therefore limited to four dates.

If more than four dates in a year are required, then please use the monthDays option in the timeStep element instead of this yearlyTimeStep

To define a yearly time step an id should be configured. Secondly the monthDays of the time steps should be configured.
In this example the yearly time step has 4 monthDays. The start attribute defines the start of the aggregation period and the
end tag defines the end of the aggregation period. The value defines the value of the monthDay itself.
