What means "Government Payday Week"

In a post from April last year was mentioned that the state boats are only running during "Government Payday Week" (I copied it). - Is this true and if: What time of the month is this week (first, last, else...)?

Payday is every second Thursday (today being payday). I believe the boats to Anguar and Kayangal only run on payday weeks - but Peleliu goes every week.
