Hosting is a coordination problem. The chicken needs 45 minutes. The salad needs 10. You need to shower and change. And the table isn't going to set itself. Working backward from "guests arrive at 7" turns the chaos into a checklist with start times.
No single dish is hard. Timing them so they all finish together, while also setting the table, getting yourself ready, and pretending you've been relaxed all afternoon. That's the hard part. Backward planning gives each task a start time so you're not doing mental math while the sauce is burning.
Set your deadline to when guests arrive. Add each step: marinate, prep sides, main in the oven, set table, shower, get dressed. Ready Time tells you when to start the first step. Follow the notifications through the afternoon and you'll answer the door with everything done. Not with an apron on and panic in your eyes.
