Build me a countdown plan for this party. Invites go out 14 days before. A save-the-date reminder at 10 days. The details message, with address and what to bring, at 7 days. A short friendly nudge for anyone who has not answered at 4 days. A thank-you the day after. Write the actual message for each step in my voice. Give me a list of dates and messages, then put each step on my Google Calendar as an event with its message in the description.
