Show HN: Exporting iCloud photos in 'per month' batches for backup and sorting

In the age of metadata-rich photos, I still like to stick to the good old photo folder. I know, I know. No database, no face recognition, no geodata – but it's super easy for me to make backups of, and I'm optimistic that my grand-grandchildren will appreciate a simple JPG in a folder named with the month's name over an obscure, proprietary (single-file?!) photo library format.

As an iPhone user, all my photos end up in the camera roll, and I don't see myself sorting them there.

So I created a very simple 'smart album' that will collect all photos taken in the current month. I'll name it properly (the first day of the next month, YYYY-MM-01, should do it) and export it when the current month has passed.

Photos on macOS lets you also duplicate (thank god) smart albums, so next month I'll just bump up the album's name and beginning/end dates.

Does that really export a month’s worth of photos? I would think it skips those of the first of the month.

(The programmer in me thinks “maybe, the code does after midnight on February 1”, but I would consider that a bug. It may seem an acceptable way to interpret these values to some, but if it were “after December 31”, you wouldn’t expect photos from December 31 to be included, would you?)
