Birthdays

Plan an adult birthday party

Think about how the birthday person likes to spend an evening. Dinner with six friends might suit them better than a surprise party. Start with an evening they’d enjoy, then set a budget and guest list that fit.

Pick one clear format

Guests plan differently for dinner, drinks, and an open house, so name the format in the invitation. A hosted dinner is the most work and is capped by your table; drop-in drinks spread arrivals across two to three hours and are far easier to run; an activity party such as bowling or a cooking class needs bookings three to four weeks ahead. Whatever you choose, do not make people guess whether they should eat beforehand.

Set the budget before the guest list

Start with a number, then fit the plan to it. For a hosted party, food and drink usually take 40 to 50 percent of the budget, the venue or rentals 15 to 25 percent, and the rest goes to decorations, cake, and extras. For a restaurant, expect roughly two to three times the menu price per person once drinks, tax, and tip are included, and say that range to guests if they are paying their own way.

Handle money directly

If guests will buy their own meal, tickets, or drinks, say so before they reply, with a realistic per-person estimate. If the host is covering the bill, state that too, so nobody arrives bracing for a split. For group gifts, name one organizer, set a contribution deadline, and collect the money before the event, not during it.

Decide whether it is a surprise

Surprises only work with a decoy plan: a believable cover story, one point of contact for leaks, and a strict rule that nobody mentions it in group chats. Ask guests to arrive 30 minutes before the guest of honor, and keep the reveal location easy to leave quickly. If the guest of honor dislikes attention, a smaller gathering is the kinder choice.

Send one useful reminder

Two or three days before, send a short message with the time, address or reservation name, parking, dress, and a ride-home option. Use the message for details guests need before setting off. Mention anything time-sensitive, such as a table held under a specific name or a door that locks at a set time.
