Presumably the right-most data point is from yesterday (3/1/23). Isn't there a potential flaw here in regards to that most recent data point? Whereas in previous months people had all month to post jobs to the monthly job posting thread, there has only been one day since the 3/1/23 job post thread was started. I think this script should be run on the last day of the month, not the first.
It you really want to model this correctly (more than just, it looks like it's going down) you would need to adjust for seasonal factors as well. At least in this data it looks like February postings are always higher than January, but this year they are not as much higher as they normally would be.

Yes, you're right. However, the trend during the last months is very clear.
From January though February (the last month with complete data) the trend was up.
