Sunday Kalogeras: Real Name, Age, Sisters, and Bio

There’s something about a family nickname that sticks—and for Sunday Kalogeras, it turned into a global brand. The 23-year-old Canadian TikTok creator leads a trio of sisters who’ve amassed millions of followers by blending lifestyle content with their Greek-Canadian heritage.

Full Name: Sunday Kalogeras (nickname Kalia) · Age (as of 2025): 23 years old · Birthplace: Edmonton, Canada · TikTok Followers: 15.2 million · Instagram Followers: 5 million · Known For: Digital content creator @sundaykalo

Seven key data points, one pattern: the most reliable information comes from a single Greek-Canadian newspaper, while most other sources repeat unverified details.

What is Sunday Kalogeras’s Real Name?

Full name and nickname origin

• Sunday Kalogeras is her public name. According to Favikon, she is a Canadian social media personality who uses “Sunday” as her first name online.
• A Greek-Canadian newspaper, The National Herald, identifies her with the name Kyriaki—the Greek equivalent of Sunday—but this remains unconfirmed by the creator herself.

Why ‘Sunday’ is used publicly

• Sunday Kalogeras has not disclosed a different birth name in any verified interview or bio. Her Instagram handle is @sundaykalogeras (Instagram).
• Some fan speculation on Reddit suggests her real name might be Kailea or Kyriaki, but these are low-confidence rumors.

Why this matters: For a creator whose nickname “Kalia” is almost as famous as her public name, the lack of an authoritative bio means every article relies on the same handful of sources.

How Old Are the Kalogeras Sisters?

Ages of Sunday, Demitra, and Eliana

• Sunday Kalogeras is 23 as of 2025, according to Famous Birthdays.
• Demitra (sometimes spelled Demetra) is reportedly 25–26 years old (The National Herald states she was born in 2006, which would make her 18 or 19—but this conflicts with other estimates).
• Eliana, the youngest, is around 19–20 based on the same source.

Birthdays and birth year breakdown

Several YouTube compilations claim Sunday was born on May 26, 2003 (YouTube), but these are unverified. The only consistent point across sources is that she was born in 2001 or 2002. The discrepancy between The National Herald (which says Demetra born 2006) and other estimates suggests ages are not settled.

The pattern: the sisters’ ages are among the most searched questions, yet no single source is authoritative enough to settle the debate.

Who Are Sunday Kalogeras’s Sisters?

Demitra Kalogeras

• Demitra is also a content creator and appears frequently in sister collaborations. The National Herald describes her as the second sister.
• Her age is disputed, but she is older than Eliana and younger than Sunday (if Sunday is the eldest).

Eliana Kalogeras

• Eliana is the youngest and active on TikTok and Instagram. She is part of the “Kalogerasisters” brand alongside Sunday and Demitra (Famous Birthdays).
• Their YouTube channel launched in 2024, as noted on Fandom.

The collective ‘Kalogeras sisters’ brand

The trio’s appeal lies in their family dynamic and Greek-Canadian identity. Favikon notes that their growth is tied to content featuring all three sisters. A Tubi series listing confirms they are recognized as a Canadian-Greek sister group.

The implication: the collective brand is stronger than any individual sister’s profile, yet Demitra and Eliana remain less documented than Sunday.

Why Is Sunday Kalogeras Called Kalia?

Origin of the nickname

• “Kalia” is reportedly a family nickname. TikTok discovery content states she is affectionately called Kalia by those close to her.
• The nickname may derive from the Greek name Kyriaki, but this is speculative.

How fans use the name

Fans and some secondary sources use “Kalia” interchangeably with Sunday. A Fandom wiki even lists her as “Sunday ‘Kailea’ Kalogeras,” although the spelling varies.

How Much Money Does the Kalogeras Family Have?

Estimated net worth of Sunday Kalogeras

Exact net worth is not publicly verified. Favikon estimates range from $500,000 to $1 million based on follower count and engagement, but this is a rough figure.

Sources of income: brand deals, merchandise, social media

• With 15.2 million TikTok followers and 5 million Instagram followers, brand sponsorships are a primary revenue stream.
• The sisters have not publicly disclosed specific deals, but their growth trajectory suggests consistent monetization.

The catch: without verified financial disclosure, any net worth figure remains an educated guess.

How Old Is Demitra Kalogeras?

Demitra’s birth year and age

The National Herald states Demetra was born in 2006, making her 18 or 19 in 2025. However, other sources place her closer to 25-26. Without an official biography, her age remains unclear.

Comparison to Sunday’s age

If Sunday was born in 2003 (per some sources), then Demitra being born in 2006 would make her the middle sister. If Sunday is 2001/2002, Demitra’s age band shifts accordingly.

The pattern: Demitra’s age is the most inconsistently reported data point across all sources.
