XXIO Day

What Is XXIO Day?

The 21st of every month is "XXIO Day" in Japan. It was established by Dunlop Sports Marketing Co., Ltd., which sells golf and tennis equipment, to mark the 20th anniversary of the XXIO brand. The purpose is to put out news about the brand each month.

Roman Numerals Hidden in the Logo

The choice of the 21st comes straight from how the brand name is written.

• Origin of the date: the logo spells the brand with the Roman numeral XXI (21), hence the 21st of each month
• The idea behind it: positioning XXIO as a hundred-year brand of the 21st century
• Brand launch: the golf brand was created in 2000
• Established by: Dunlop Sports Marketing Co., Ltd.
• Purpose: to share the brand's latest news monthly

Part Number, Part Letters

"XXIO" is the Roman numeral XXI with an O added. Readers who know Roman numerals catch the intent; those who do not simply remember a string of letters. The anniversary's date puts that same device to work.

Tips for Marking This Day

• Brush up on Roman numerals (X = 10, I = 1)
• Look for hidden numbers or meanings in brand names around you
• Read up on clothing and gear for cold-weather golf
• Get ready for any round you have planned over the holidays

When the Name Picks the Date

A name built around the 21st century ended up as an anniversary on the 21st of each month. Naming decisions can echo in unexpected places.
