lol Sorry for the pain of the stats system! I love them myself as a player, but this has been hell to code, so my next games will go back to the old-fashioned affection points system through choices and that's it!
About the dates, the Louvre date takes place in the mornings (any day), the Eiffel tower in the afternoons (any day on the last two weeks, but I'll add it sooner to avoid skipping it if you get the good end early), dinner date is on Friday/Saturday night (it depends on if there's an exhibition event that week), and Montmartre visit is on Sundays. They should have gone to the Louvre the next day you asked, but I think that's the day Paul gets an unexpected visit that takes all the weekend...
