Users often ask 3 types of questions about HOUR: formula errors, nested usage, and automatic recalculation after import; this FAQ includes 3 common answers.
FAQ
What should I check if the HOUR function returns an error?
- Check whether the formula syntax is correct, including the function name and parentheses.
- Check whether the input is a valid time value, date-time value, or a reference that can be used in time calculation.
- Check the data type of the referenced field and avoid passing plain text that cannot be interpreted as time.
Can I use HOUR together with other functions?
- Yes. You can first use HOUR in a formula field to extract the hour from a time value.
- Then use the returned result as an input or condition in another formula.
- Save the formula and review the combined result, then adjust it if needed.
Will HOUR update automatically after I import data?
- If the formula field already exists, imported records are calculated with the current formula.
- When the source time value changes, the formula field result updates with it.
- If no result appears, check whether the imported field format can be used for time calculation.
