How to write your own half birthday wish

• Use the “half” theme: halfway, half a year, ½, half a cake, half the song.
• Mention the age as a fraction, such as 7½ or “halfway to 30”.
• Look ahead: half birthdays are a natural moment to wish someone a great next six months.
• Keep it short. A half birthday is a small celebration, so one or two lines is plenty.
• Add a small gesture. A card cut in half, a half cake or a small treat. See half birthday gift ideas and half birthday cake ideas.
