Where I live, in December, it’s already night by 4pm, whereas in July, 4pm isn’t even the peak of heat yet. But if someone said “good evening” to me at 4pm in either of them, I’d prob accept it either way, and I’m a meteorologist
Also: In the UK and the US, the typical meteorological standard is just to split seasons by month (DJF MAM JJA SON) for easy stats reasons, but other countries have entirely different standards based on climate. Different people have different definitions and it’s completely fine
AuDHD and completely caffeine free (and stimulant/meds/drugs free too). Caffeine definitely doesn’t work for me like it does for other people - makes me sleepy and headachey. I’d rather just work with what I’ve got, (noise cancelling headphones + being inflexible) even if it has limitations
