Is social security 9 months a year or half a year?

This social security payment method cannot be counted as one year or half a year.

One-year social security refers to continuous payment of social security 12 months, not annually. So nine months can't be counted as a year, nor can it be counted as half a year.

Specifically, the payment period of social insurance is calculated according to the number of months actually paid. For example, if you pay social security for 9 months, then the social security payment period is 9 months.
