Crate key sale clarification post II

[worshipped]

This is my second post asking for clarification of the crate key sale. Generally the crate key sale is supposed to be on the 31st of every month. But for the past three months its been on 16/17(march/april/may). But now there is another sale today(31 may 2021). So my question to the devs is that,is there any criterion atm for deciding which day to put crate keys on store? Cuz i would really appreciate it.
