A long time ago I loaded up my large gallery of medium sized jpgs that I keep on the web ((`1800-3600 pixels on the long side), but I've not used it since then.. Looking at that now I see that I can sort by date, which includes year/month, not by day, but I'm not sure how I loaded them.
You can create albums, but I don't know if you can create albums within albums (for example so that you could sort by year - month - day).
You CAN upload a directory which is what I'm doing now as a test. Raw files from 4/21/2020. 1GB in total. 5 mins for 5 images so far (raws from a 24mp APSC camera), but it includes a 533mb DNG pano and a load of xmp files so will be interesting to see what it does with the xmps and how I can filter.
