National Heather Day

Next celebratedThursday, December 3, 2026

Every December 3, people online hand someone a sweater, because a 2020 song's opening line names that exact date. The ritual has returned every year since, and it still baffles anyone who meets it cold.

HOW THE HOLIDAY CAME TO BE

A singer put a name on a date his own song had already picked.

On 3 December 2020 the singer Conan Gray posted from his own account that it was officially heather day, noted that nobody had given him a sweater, and offered one to his followers. The date is the one named in the opening line of his 2020 song Heather.

INTRO

The girl in the song was the rival

The Heather this day is named for is not being honored. In the song that gave the date its meaning, she is the girl the singer's crush picked instead.

Conan Gray put the track on his first album in March 2020. Its opening line names the third of December and a borrowed sweater, and that line is the entire reason the date carries the name.

So the ritual is a small kindness built on a song about envy. People hand a sweater, a hoodie or a jumper to someone they love or fancy, and every December a fresh crowd arrives asking what is going on.

ORIGINS

Heather Day history

CHAPTER 01

A moor plant that became a girl's name

Heather was a plant long before it was a person. It reaches modern English through Middle English hather, and older still it was a Scottish and northern English name for the low shrub that covers open ground. Only in the late nineteenth century did anyone start handing it to a child.

America took it up slowly. The name does not surface in the national naming record until 1914, and then only eight times, before a long climb that peaked in 1975, far above where the name sits today.

CHAPTER 02

A song about wanting to be somebody else

In March 2020 Conan Gray put Heather on his first album. It was a track, not a single, and it took months to travel: Britain charted it in August, and America followed days later.

Gray has said the song came out of four years of loving someone in high school who was with a girl of that name. The video, by his account, was his way of becoming everything he envied about her.

CHAPTER 03

The day names itself

Then the calendar caught up with the lyric. On the first third of December after the song charted, Gray posted that it was officially heather day, said nobody had given him a sweater, and made one for everyone reading.

Nobody has established who first used the phrase, and his wording suggests he was answering chatter already underway. What is fixed is the date of the post, captured by the Internet Archive within minutes of going up, which remains the earliest dated trace of the day.

TIMELINE

Timeline

The name reaches the national record

Heather appears in the Social Security Administration's national data for the first time, carried by eight girls. The agency leaves out any name used fewer than five times in a year, so this is the year it clears that bar rather than the year it began.

The high-water mark

Heather is given to 24,301 girls in the United States and ranks third for the year. It is the highest the name ever reaches, and it never climbs back.

The song arrives buried on an album

Conan Gray releases his debut album Kid Krow, with Heather as one of its tracks rather than a single.

Britain charts it first

Heather enters the UK Official Singles Chart on 20 August and climbs to number 17, staying on the chart for thirteen weeks.

The day gets its name

Gray posts that it is officially heather day. Nobody had given him a sweater, so he makes one to share. The Internet Archive captures the post about two minutes later.

Five years on, still explaining itself

UK outlets run fresh explainers as the sweater exchange trends again, describing a trend that confuses people every year.

WHY THIS DAY MATTERS

Why We Love National Heather Day

Language

The name stopped being only a name and started being a description.

By early September 2020 Vox was covering the name as internet shorthand, under the headline Everybody wants to be Heather. Bustle explains a Heather as the person your crush is in love with, a sense that has since softened enough to work as a compliment.

Record

The starting year is checkable, and often reported wrong

UK coverage has dated the trend's start to 2021. The post that named the day is dated 3 December 2020 and was archived the same day, so 2020 is the year the record actually supports.

Edge

The comparison cuts both ways

The word is not always kind to the person using it. Bustle notes that while the usage is mostly joke-y or positive, it can strike a negative, low self-esteem tone once people start measuring themselves against a perfect Heather.

I just thought that maybe nobody would relate to it, I thought that maybe I was insane for feeling the way I felt.

GET INVOLVED

How to Celebrate National Heather Day

EDITOR'S PICK

Hand over the sweater

The observance has one native gesture: give a sweater, hoodie or jumper to someone you love or fancy. That gesture is the entire observance.

PLAY

Play the track that set the date

Heather sits on Kid Krow, Conan Gray's first album, where it arrived in March 2020 as an album cut rather than a single. Listening to the opening line explains the date faster than any explainer does.

SEND

Send a note to the Heathers you know

The day travels under a name, and plenty of people carry it. A message to the Heathers in your phone fits the version of this day that has nothing to do with anybody's crush.

Test your knowledge

How well do you know National Heather Day?

1 / 8

Why does this day fall on December 3?

Answer

No. The United Nations list of international days and weeks carries 246 dated entries and none of them is Heather Day, so it has no standing as an international observance.
