When is Siblings Day?

It's national siblings day on the 10th April.

A Brief Look into the History of National Siblings Day

Founded by New Yorker Claudia Evart after she lost both her siblings early in life, National Siblings Day was initially celebrated in 1995. It was created, quite simply, as a day to honour and appreciate your siblings - not run away from them when they aim vegetables at your head. Serious frustrations aside, having a sibling is much like having a built-in best friend.

How to Celebrate?

The day can be celebrated in various ways. Some choose to send sentimental cards, while others dust off old photos and post them online as a nostalgic nod to past shenanigans. But it's not all about the past, it's also a great time to focus on strengthening those sibling bonds moving forward. We recommend hugs, not broccoli.

History behind the term 'Siblings'


Introduction of the term 'sibling'

The term 'sibling' was first introduced in the English language in 1623. It is derived from the Middle English word 'sibb', which means 'kinsman' or 'relative'.


Usage in legal context

In 1838, the term 'sibling' started to be used in a legal context, referring to individuals who share at least one biological or adoptive parent. It was particularly used in inheritance laws, where siblings were entitled to certain rights and responsibilities.


Psychological study of sibling relationships

In 1903, pioneering psychologist G. Stanley Hall conducted a study on sibling relationships, highlighting their significance in child development and socialization. This study shed light on the various dynamics and complexities of sibling relationships, including rivalry, cooperation, and emotional bonds.


Recognition of 'sibling rivalry'

During the 1960s, 'sibling rivalry' gained widespread recognition as a term describing the competition and conflicts between siblings. This phenomenon was often attributed to a desire for parental attention and scarce resources, leading to a better understanding of the complexities within sibling relationships.


Focus on sibling support

In the 1990s, there was a growing recognition of the importance of sibling relationships in providing emotional support and long-term companionship. Research emphasized the positive impact of strong sibling bonds on individual well-being and highlighted the role of siblings in cultivating empathy, social skills, and resilience.
