**DateMath** is a field on the [Entity](/graphql/entity.md) root type that represents any characteristics that are set up with DateMath on a given Rightsline record.  DateMath is an array of objects with the following structure:

```graphql
{
    entity(id: 1, charTypeId: 4) {
        dateMath {
            result
            dateMathCalcId
            isCalculated
            compareToDate
            dateOption
            recalcOption
            conditionOption
            parentCalcs {
                dateMathRelId
                yearQuantity
                monthQuantity
                weekQuantity
                dayQuantity
                dayUnit
                isPriorTo
                sortOrder
                entityTitle
                entityTypeId
                id
                tagLabel
                label
                characteristicId
            }
            childCharacteristic {
                type
                entityTitle
                entityTypeId
                id
                tagLabel
                label
                characteristicId
            }
        }
    }
}
```
