 ## makeDate32
 
-Like [makeDate](#makedate) but produces a [Date32](../data-types/date32.md).
+Creates a date of type [Date32](../../sql-reference/data-types/date32.md) from a year, month, day (or optionally a year and a day). 
+
+**Syntax**
+
+```sql
+makeDate32(year, [month,] day)
+```
+
+**Arguments**
+
+- `year` — Year. [Integer](../../sql-reference/data-types/int-uint.md), [Float](../../sql-reference/data-types/float.md) or [Decimal](../../sql-reference/data-types/decimal.md).
+- `month` — Month (optional). [Integer](../../sql-reference/data-types/int-uint.md), [Float](../../sql-reference/data-types/float.md) or [Decimal](../../sql-reference/data-types/decimal.md).
