I am using AUTO ARIMA for forecasting. But it is not detecting 'seasonality
term' of its own for any data.
Is there any other method by which we can detect seasonality and its
frequency for any data?

Is there any method through which seasonality and its frequency can be
automatically detected from ACF plot?
