National Sisters Day 2027: Date, Meaning, Wishes and Gifts
National Sisters Day 2027 falls on Sunday, 1 August. The date moves each year because the day is observed on the first Sunday of August rather than on a fixed date.

It is not a public holiday and has no official standing anywhere. It grew out of American greeting card and social media culture and spread from there, and it is now widely marked in India too, usually with a post, a message or a small gift.

Where the day comes from
There is no founding charter or single originator that can be verified the way there is for Siblings Day. National Sisters Day is best understood as a modern social observance, popularised through greeting cards, retail promotions and then social media, rather than something declared by a government or institution.
The vagueness is part of why the day works. It covers biological sisters, cousins, sisters in law, and the friends people call sisters without any of the ritual structure that a traditional festival would impose.
Sisters Day, Siblings Day and Raksha Bandhan
These three get confused constantly, so here is the difference.
Occasion | When | What it marks |
National Sisters Day | First Sunday of August. 1 August 2027 | The bond between sisters. Modern, informal, no rituals. |
National Siblings Day | 10 April, fixed | All siblings. Founded by Claudia Evart in 1995, on her late sister Lisette's birthday. |
Raksha Bandhan | Shravana Purnima, July or August | A sister ties a rakhi on her brother's wrist and he pledges protection. An ancient Indian festival with a full ritual. |
Bhai Dooj | Two days after Diwali | The other Indian brother and sister festival, marked with a tilak and a shared meal. |
The key distinction: Raksha Bandhan and Bhai Dooj are between brothers and sisters. Sisters Day is between sisters.

• Something she has mentioned wanting and not bought for herself.
• A handwritten letter, especially if the two of you usually communicate in one line texts.
• A subscription to something she uses, such as an audiobook or streaming service.
