When sending out invites—whether for a wedding, party, corporate event, or a baby shower—how you write the date matters more than you think. A well-structured invitation date format sets the tone of your event and reflects its formality. Should you write it out in full? Include the day of the week. Use numbers or words?

Best Practices for Writing Dates on Invitations
- Spell out the day and month for formal events.
- Use consistent formatting across all invite materials (main card, RSVP, inserts).
- Capitalize the first letter of days and months.
- Avoid ordinal numbers with digits in formal writing (e.g., don’t write “June 22″—write “the Twenty-Second of June”).
- Time of day can be in words (“Four O’Clock”) or numbers (“4:00 PM”), but match the tone of your event.
Bonus: RSVP Date Format Suggestions
Here are the proper ways to write RSVP deadlines:
- Formal: Kindly respond by the Tenth of May, Two Thousand Twenty-Five.
- Simple: RSVP by May 10, 2025

Always make the RSVP date at least 2–4 weeks before the event.
