Use Case 4: Convert Hours in the Day to Day Parts
This use case converts hours in the day into day parts; for example, morning or afternoon.
| Raw Data | Goal |
|---|---|
| Column named Hour of Day. | Create the formula field “Day part” that assesses the hour of the day and determines if the value is Morning, Midday, Afternoon, Evening, or Overnight. |
- For Field Label, enter Day part.
- For Formula Return type, select Text.
- In the syntax editor, enter the formula: IF(sourceField['Hour of Day'] >= 6
&& sourceField['Hour of Day'] < 10, 'Morning', IF(sourceField['Hour of Day'] >= 10
&& sourceField['Hour of Day'] < 15, 'Midday', IF(sourceField['Hour of Day'] >= 15
&& sourceField['Hour of Day'] < 19, 'Evening', IF((sourceField['Hour of Day'] >= 19
&& sourceField['Hour of Day'] < 24) || (sourceField['Hour of Day'] >= 0 &&
sourceField['Hour of Day'] < 6), 'Overnight', "Unclassified")))).If the raw data doesn’t have a separate column for Hour of Day, you can use the same formula by reading in a Date with Timestamp and parse out the timestamp.
- In the test input box, validate the formula using these combinations.
- “Hour of Day” with the value of “6” returns “Morning”.
- “Hour of Day” with the value of “12” returns “Midday”.
- “Hour of Day” with the value of “18” returns “Evening”.
- “Hour of Day” with the value of “19” returns “Overnight”.
- “Hour of Day” with the value of “23” returns “Overnight”.
- “Hour of Day” with the value of “0” returns “Overnight”.
- “Hour of Day” with the value of “5” returns “Overnight”.
- Click Save.
