Eight key data points pulled from public profiles:

What is Sunday’s real name, Kalogeras?

Sunday Kalogeras is the name she uses on all major social platforms — there’s no evidence of a different legal name being used publicly. Her Instagram handle is sundaykalogeras and her TikTok handle is sundaykalogeras. We’ll get into the “Kalia” nickname in a moment, but first, here’s what’s known about her age and online presence.

How old is Sunday Kalogeras?

Multiple secondary profiles, including Famous Birthdays (user-contributed database), list her birth date as May 26, 2003, making her 23 years old in 2025. A profile from GenZ Times (entertainment news site) also states she was born on May 26, 2003, and adds that she is 22 in 2025 — a discrepancy that likely depends on whether the article counts from her last birthday. The 2003 year is consistent across sources.

What is Sunday Kalogeras’s Instagram handle?

Her Instagram handle is sundaykalogeras, where she has 5 million followers as of early 2025 (Famous Birthdays (user-contributed database)).

The pattern: There’s broad agreement among tier‑2 and tier‑3 sources on her name, birth year, and handle. However, the exact day (May 26) is only backed by user-contributed data, not official records.

The implication: what’s directly observable on her accounts is trustworthy; the birth date remains the sole gap requiring primary confirmation.

Why do they call Sunday Kalogeras Kalia?

On several fan pages and biographies, Sunday is referred to as “Kalia.” One profile from TheCityCeleb (celebrity biography site) gives her birth name as Sunday “Kailea” Kalogeras. Another from OreateAI (AI-generated content platform) suggests her middle name might be Kayleigh. None of these come from Sunday herself or from verified primary sources.

Is Kalia a nickname or a middle name?

It is not publicly confirmed. The name “Kalia” appears only in third-party bios, and the sisters do not use it on their official social media handles or channel descriptions. The variation between “Kailea,” “Kalia,” and “Kayleigh” suggests that these are likely guesses by fan wikis rather than authoritative information.

What this means: Any article claiming to know the exact spelling or origin of “Kalia” is relying on unverifiable secondary sources. Readers should treat the nickname as speculative.

The catch: the nickname “Kalia” has no verified origin, and every new variation weakens its credibility further.

How old is Sunday Kalogera’s dad?

Publicly available information does not disclose the father’s age. The Kalogeras family maintains privacy on parental details. No interview, official bio, or social media post from the sisters mentions their father’s age. The only reference comes from group descriptions that list the family as “Greek-Canadian,” but without specific ages (The SportsGrail (fan blog)).

The catch: Because the sisters have chosen to keep their parents’ lives private, any age or occupation claimed online is almost certainly speculation. No authoritative source exists.

Who is the prettiest Kalogera’s sister?

Beauty is subjective; there is no official ranking. The three Kalogeras sisters — Sunday, Demitra Mia, and Eliana — each have their own online followings. According to Wikitubia (Fandom wiki), the group consists of Sunday, Demitra Mia, and Eliana. Sunday is described as the eldest in multiple profiles (The SportsGrail (fan blog)). However, the exact birth order and height differences are not publicly stated.

Who’s the oldest between the Kalogeras sisters?

Several profiles label Sunday as the oldest. Neither Demitra Mia’s nor Eliana’s ages are confirmed in any primary source. The only consistent statement is that Sunday was born in 2003.

Which Kalogera sister is the tallest?

Height is not mentioned in any of the available research notes or public profiles. This question remains unanswered.

The implication: Comparisons among the sisters are driven by fan curiosity, not data. Until the sisters themselves share personal details, any ranking of beauty, height, or age is guesswork.

How are the kalogeras so rich?

The sisters generate income through social media sponsorships, brand deals, and merchandise. With a combined following of over 15.2 million on TikTok and 5 million on Instagram (Famous Birthdays (user-contributed database)), their influencer reach is substantial. Several profiles estimate the group’s net worth at $2 million to $3 million (TheCityCeleb (celebrity biography site); BiographyLifes (celebrity database)). However, these figures are not independently verified.

What is Sunday Kalogeras’s net worth?

No verified net worth figure exists. The $2–3 million range cited by secondary sources appears to be a rough estimate based on follower counts and typical creator earnings. MuscleHustles (entertainment site) repeats a similar range.

How do the Kalogeras sisters make money?

Their revenue likely comes from sponsored TikTok and Instagram posts, affiliate marketing, and merchandise sales via their YouTube channel (launched March 2024). The YouTube channel “Kalogeras Sisters” serves as a central hub for content, and its description links to additional income streams. The family is described as “extremely wealthy” by The SportsGrail (fan blog), but that claim has low confidence — no primary financial documentation supports it.

Why this matters: For brands considering partnerships, the sisters’ reach is real, but the exact financial returns remain opaque. Any net worth data should be cited as “reportedly” until audited.

The pattern: follower counts drive real income, but the specific dollar figures remain secondary-source estimates, not audited facts.

Sunday Kalogeras’s birth date is listed as May 26, 2003, with 15.2 million TikTok followers and 5 million Instagram followers, according to the user-contributed database Famous Birthdays.

The Kalogeras sisters’ collective net worth is estimated at $2 million to $3 million, though these figures lack independent verification, notes TheCityCeleb, a celebrity biography site.

Frequently asked questions

For anyone trying to understand the Kalogeras sisters’ rapid rise, the data that is verifiable — follower counts, platform handles, and Canadian roots — is solid. The unknowns—nickname origins, father’s age, exact net worth—highlight how much of the influencer economy still runs on guesswork. Journalists covering the Kalogeras family should wait for a primary interview or continue treating every dollar and nickname as unconfirmed.
