Looks like you may have figured this out, but yes, Gran's House is not on Day 1 anymore.
In general, some events and locations have changed what Day they appear on, so walkthroughs for the original game aren't 100% accurate for the remake. There is always the in-game hint system you can access via the Journal icon in the lower left, though, which will always include a hint of what things are required to end each day if you're stuck (among other more specific hints).
