What National Daughters Day is
National Daughters Day is an informal observance in which parents, grandparents, and other relatives mark the daughters in their lives, most visibly by posting about them on social media. In the United States it is kept on September 25.
It carries no official status. There is no presidential proclamation and no act of Congress behind it, which puts it in a different category from Mother's Day, designated by Congress in 1914. Snopes, reviewing the day in 2021, described it plainly as not an officially designated special day in the United States. That is not a knock on it. Most of the days on any given calendar are unofficial, kept because enough people decided to keep them. But it does mean there is no authority to appeal to when sources disagree about the date, which is exactly what has happened here.
No single body organizes the day, and nothing has been registered or incorporated around it. What it has is a hashtag and a widely shared date. This site's National Pepperoni Pizza Day page documents the same kind of blank: National Day Calendar registers that date too, while saying plainly it is still researching who actually started it.
Which date to use, and who uses which
Three different dates circulate, and they are not simply competing answers to the same question. Two of them belong to observances that are genuinely distinct.
September 25 is the American answer. National Day Calendar lists National Daughter's Day on September 25, and the large calendar aggregators that most search results surface, including National Today and Days of the Year, agree. Snopes found that US social media activity around the day settled on the last week of September, typically September 25 or 26, starting around 2015.
The fourth Sunday in September is a different observance with a different name. National Day Calendar maintains a separate entry for International Daughters Day on that rule, and describes it as originating in India. This is the working date across India: in 2024, when September contained five Sundays and the fourth and last Sundays fell apart from each other, Indian coverage marked the day on Sunday, September 22, the fourth Sunday, not September 29. That settles a small ambiguity in the wording. Snopes, cited elsewhere on this page, is among the sources that call it the final Sunday; National Day Calendar's own published table for the international entry runs 22 September 2024, 28 September 2025 and 27 September 2026, which is the fourth Sunday in each case, not the last. The rule is the fourth.
October 1 appears once, in National Day Calendar's own note that the day is observed on that date in some places. The entry does not say where, and no other source consulted here supports it. Treat it as a loose end, not a real fourth option.
The practical guidance: if you are in the US and want the date most people around you are using, September 25 is it. If you are marking the day with family in India, or you are working from an international calendar, the fourth Sunday in September is the one that will line up with everyone else. In many years the two land within days of each other, which is part of why they blur together. This calendar has an even more mobile entry: this site's National Wife Appreciation Day page covers a date pinned to the third Sunday in September, shifting against the regular calendar every single year.
Where the origin story comes from, and what it actually supports
Nearly every page about this day tells the same origin story: the Indian greeting card company Archies Limited created Daughters Day in 2007 to counter the stigma attached to having a daughter rather than a son. Unusually for a widely copied claim, there is something real underneath it. In a 2007 interview quoted by Snopes, Archies managing director Anil Moolchandani discussed the company's push behind the occasion, framing it as an effort to counter gender discrimination and to make the case that a daughter is no lesser than a son. He described the idea growing out of a conversation with census officials about the situation of the girl child, followed by the company canvassing parents and members of the public.
Two things get lost when that story is compressed into a one-line origin. The first is that Moolchandani claimed partial responsibility, not authorship. The second, and more consequential, is that the observance he was describing is the Indian one on the fourth Sunday in September. Using it to explain the American September 25 date quietly merges two observances that the same sources otherwise keep apart. A greeting card company promoting a card-buying occasion also has an obvious commercial interest in being remembered as its originator, which is worth holding in mind without treating it as disqualifying.
The older American thread runs somewhere else entirely. Snopes found the earliest reference to a National Daughters Day in a December 1932 news article about a celebration run by a Vermont chapter of the Daughters of Union Veterans, with scattered mentions following in 1939, 1940, and 1949. Then, in the spring of 1950, the idea reached Congress. The Congressional Record for March 31, 1950 shows Representative Tom Steed of Oklahoma introducing, by request, "H. R. 7938. A bill designating the second Sunday in April as National Daughter's Day," referred to the Committee on the Judiciary. It died there. The phrase "by request" is a standing congressional convention indicating that a member is introducing a measure on someone else's behalf rather than championing it, so even this record does not name the person behind the idea.
After the 1950s the day drops out of American archives almost entirely, and does not reappear until scattered social media mentions in the 2010s. Snopes traced its modern spread to posts by prominent celebrities from 2015 onward rather than to any organization or campaign. So the honest position is that the September 25 observance has no traceable founder. What can be documented is a failed 1950 bill for a different date, and an Indian observance on a different date whose promoter took partial credit. This site's National Wildlife Day page runs into a related but different problem: a founder is actually named there, Colleen Paige, yet sources can't agree on whether she started it in 2005 or 2006.
How the day is actually marked
In the US the day lives almost entirely on social media. The typical observance is a parent posting photographs of a daughter with the hashtag #NationalDaughtersDay. There is no ceremony attached, no traditional gift, and no widely followed convention about who the day is for. Adult daughters, young children, stepdaughters, and daughters-in-law all get included depending on the family.
In India the day retains more of its original framing. National Day Calendar describes the observance there as directed at the status of the girl child and at the stigma some families still attach to daughters. Gifts and cards are common, unsurprisingly given the day's commercial promotion, but so is public messaging about girls' education and equal treatment.
One practical note about the social media custom. In 2021, a widely forwarded warning claimed the day was manufactured by foreign actors to harvest family photographs for facial recognition. Snopes rated that claim False, finding no evidence for it and pointing out that the reasoning does not hold up, since photographs of children are already posted online in enormous volume without any need to engineer a trend. Ordinary privacy judgment about posting pictures of children applies here as it does any other day, but there is no specific plot to worry about. This site's National Burrito Day page covers an observance with the opposite shape of problem: a date that genuinely does move every year, the first Thursday of April, attached to no named founder at all.
Days it gets confused with
International Daughters Day, the fourth Sunday in September, is the closest neighbor and the source of most of the date confusion. It is a separate listing with a separate history, not an alternative name for the September 25 day.
National Son's and Daughter's Day falls on August 11 and covers children of both sexes. Its own origins are similarly murky. National Day Calendar traces an August 11 observance back to a 1988 Canadian newspaper mention and describes earlier, unrelated efforts, including a 1936 push by J. Henry Dusenberry in Missouri and a 1970s congressional request that proposed the last Sunday in January. Like National Daughters Day, it never became official.
The International Day of the Girl Child, October 11, is the one observance in this cluster with unambiguous provenance. The United Nations General Assembly adopted resolution 66/170 on December 19, 2011 to establish it. If you want a date in this territory that is documented, not inferred, that is the one.
Take Our Daughters to Work Day, which began in 1992 and later expanded to include sons, is sometimes cited as a precursor. Snopes notes it as a separate development that ran during the decades when National Daughters Day itself had vanished from American records. Food-themed observances run into an identical gap: this site's National Nachos Day page can document exactly when the dish itself was invented, 1943, while still finding no founder on record for the November 6 observance built around it.
