Programming Skills Question

I have a quick question about the programming skills setup this year. I know that only the top 30 qualify for worlds but how long do we have until they stop letting people get into the top 30? I have not yet found a date. The list on Robotevents only says that the green shows who would qualify if the season ended today but there is no specific date. Does anyone know when this date is exactly. thank you.
