On April 29, celebrate the zipper because it is Zipper Day!
National Zipper Day is observed each year on April 29th. This day celebrates something that we often do not think about and just automatically take for granted.
There are 4.5 billion zippers of all kinds consumed in the U.S. per year. That’s 14 zippers for every American per year.
From handbags and jackets to trousers and boots, it really is impossible to imagine life without zippers. They are so widespread it is easy to take them for granted. This is where Zipper Day comes along to remind us of the origin and history of this truly omnipresent invention.
Who invented the zipper?
The exact birthday of the zipper is debated, but Zipper Day is traditionally celebrated on April 29. On that date in 1913, Swedish-American scientist and inventor Gideon Sundback received a patent for a curious contraption he called “hook-less fastener”. Although similar inventions had been around since the 1850s, his version is widely accepted as the first modern zipper.
The continuous fastening line found numerous applications and grew in popularity, also thanks to the US Army who stepped in as an early adopter. Sundback’s invention was assured success when the US Navy bought 10,000 zips for use on new flying suits in the First World War.
Functional, fashionable, infinitely adjustable – these qualities of Sundback’s design have helped popularize the invention and practically make every day Zipper Day.
Zippers are big business. YKK group is the biggest zip maker, which is why the letters YKK are on so many zips. Every year, YKK produces enough zippers to wrap around the world 50 times. That’s 1.2 million miles of zippers! YKK makes airtight zippers for spacesuits, flame retardant zippers for fire suits, airtight zippers for bagpipes and zippers for fish farm nets. You can find YKK factories in 71 countries. The company makes zippers in 9,500 colors and has 20 shades of black in its color library.
I think it is a very funny holiday
I prefer zippers because they are more comfortable and reliable then buttons. I’m sure that zipper is one of the best inventions ever made.

Interesting! Brings new meaning to the phrase “zip it up”.
zip it up (slang) – a rude and angry way of telling someone to stop talking: Just zip it – I’m tired of listening to you complain.
I have never heard about this day! The zipper is a very good invention. On the one hand zippers are comfortable but on the other hand zippers of bad quality break easily. Buttons are less comfortable , but they never break! Both zippers and buttons can decorate your clothes. I would prefer either a good zipper or beautiful buttons. I would like to have a zipper manufactured by YKK. Most of my clothes are with zippers.
I’ve never heard about this day. I think it’s a strange holiday. As for me a zipper is a very cool invention. They are comfortable, colourfull, practical and fashionable. When comparing a zipper and buttons I’ll choose a zipper. I’ve been suprised when I read that there are 4.5 billion zippers of all kinds consumed in the U.S. per year. We should be grateful to Gideon Sundback. I am sure that without zippers our clothes, wouldn’t be so comfortable.
I prefer zippers. I have zippers on clothes, bags, shoes and pencil cases. I have never heard about Zipper Day before. I think that Zipper Day is a funny holiday.
I prefer a zipper. I have many clothes and things which zip. My bag has a zipper, my pencil case has a zipper, etc. I haven’t heard about this holiday.
