# days

Simulation property for setting the number of days for a simulation.

## Synopsis

days = <number>


## Description

This probably defines the length of the simulation in days. If this property is $$0$$ or not defined, then an end_date setting is required to define the last day of the simulation. This property can only appear in a simulation block.

The value for days should be a non-negative number representing the number of days in the simulation.

## Examples

The following sets the end date of a simulation to Dec 31st, 2020. The end_date is used since the value of days is zero.

simulation {
locations = Pittsburgh_PA
state_date = 2020-Jan-01
end_date = 2020-Dec-31
days = 0
}


In this example, days is set to a positive value ($$10$$) so the end_date is ignored and the simulation runs for 10 days, until January 11, 2020.

simulation {
locations = Pittsburgh_PA
state_date = 2020-Jan-01
end_date = 2020-Dec-31
days = 10
}
