Practical Tips: When and How to Send Your 45th Birthday Message

Sending the message is just as important as writing it. Here is how to make sure it lands perfectly.

Card vs. Text: Choosing the Right Format

For a 45th birthday, the medium matters.

• Text/Social Media: Great for humor (Section 1) or casual acquaintances. It’s immediate and fun.

Perfect Timing: When to Deliver Your Wish

• The Midnight Text: Best for best friends and siblings. It starts their day with love.
• The Dinner Card: If you are attending a party or dinner, save your deep, sentimental message for the physical card you hand them. It serves as a keepsake they can look back on.
