Measure distinct year from a date in Power BI

[Cakz Primz]

Dear MrExcel,

I have a table, SalesTable with a column header OrderDate, which contains date.
In column OrderDate, I have data of order date, between year 2017 until year 2020 (2017, 2018, 2019, 2020)
How do I measures in DAX to know that the distinct year is 4?

# Years =
DISTINCT(SalesTable[OrderDate].[Year])

Thank you very much
