yes, and the first 15 days is spent in full quarantine. That is why it was extended to 45 days, so with the single extension a tourist could still spend 60 days total in Thailand. The problem is the money requirement for the type O year extension is not based on 60 days, but two months, no matter how many days are in the months. Also, during that quarantine period the person can not open a Thai bank account.
