After you file

Do you know if its exactly 6 months? Asking because on the website for my child support payments, it says pending for the money and the date posted was May 15th. I know 180 days will be next Wednesday Nov.11th. So im wondering, is it just 180 days including weekends and holidays? Or are weekends and holidays excluded from the 180 days. This is so confusing to me as I never have had a large payment come in before. I have barely had any child support given for my son within the 6 years his father has been on it. Any help would be so appreciated!! Thanks in advance!
