Anki manual states that “cards that cross a day boundary are scheduled on a per-day basis like reviews are.” I put my first step as 1.5 days so if learn new cards in the evening, I would not get them the next morning, but instead the following day. However, I noticed if I learned new cards at around one o’clock in the afternoon, they would also get pushed till day after tomorrow. I didn’t want that, so I put it at 1.33 days. Even so, card done this evening is scheduled for tomorrow. Can anyone explain what is going on? Especially why in the latter case it did not get scheduled for the 15th? My day boundary is set at 4 hours after midnight, if that matters (or is the day boundary just midnight?).
