Sunday Kalogeras Real Name, Age, and Sisters

If you’ve scrolled through TikTok lately, you’ve probably seen a trio of sisters who’ve turned family banter into a content empire. The middle sister, Sunday Kalogeras, is the quiet engine of the operation — and behind her sunny handle lies a real name most fans don’t know.

Full Name: Kailea Sunday Kalogeras ·
Age (2025): 22 ·
Birthday: May 26, 2003 ·
Birthplace: Edmonton, Canada ·
TikTok Followers: 15.3 million ·
Instagram Followers: 5 million

Six key data points, one pattern: the facts that are consistently reported across multiple biography databases hold up, while claims that vary site-to-site — like her middle name spelling or relationship status — remain unverified.

What is Sunday’s real name, Kalogeras?

Kailea Sunday Kalogeras birth name

Sunday Kalogeras’s real name is Kailea Sunday Kalogeras, a detail consistently reported by the Famous Birthdays biography database. Several secondary biography sites offer variations — one lists it as “Sunday Kayleigh Kalogeras” (GenZ Times) and another as “Sunday Kayleigha Kalogeras” (Chronical Heroes) — but these tier-3 sources carry lower confidence. The most authoritative repeat appears across multiple language editions of Famous Birthdays (French, Portuguese), all clocking May 26, 2003 as her birthdate.

Why she uses Sunday publicly

Sunday is the middle name she adopted as a public alias. Her older sister Demitra reportedly calls her “Kailea” to distinguish between her birth name and her chosen handle. This dynamic is noted in the Wikitubia community wiki, which describes the three sisters as sharing a Greek-Canadian identity and a joint YouTube channel called Kalogeras Sisters.

Who is the oldest Kalogeras sister?

Ages of all three sisters

Demitra Mia Kalogeras is the oldest of the three sisters, followed by Sunday (Kailea), with Eliana as the youngest. Their age gap is roughly three years between each sibling — Demitra is 24, Sunday is 22, and Eliana is 19 as of 2025. This birth order is confirmed across the Famous Birthdays group page and the Wikitubia community wiki.

Birth order and positions

• Demitra Mia Kalogeras — oldest (24)
• Kailea Sunday Kalogeras — middle (22)
• Eliana Kalogeras — youngest (19)

The pattern: age reporting for all three sisters is consistent across tier-2 sources, with no contradictory claims for birth order.

How old are the Kalogeras sisters on Sunday?

Sunday Kalogeras age 22 (born May 26, 2003)

Sunday turns 22 on May 26, 2025, a date stamped across Famous Birthdays and echoed by Biography Hive. Some sites from 2025 still list her as 21 (SocialStarAge), a lag common in biography databases that haven’t updated for a birthdate that falls later in the year.

Demitra Kalogeras age 24

Demitra is 24 as of 2025, making her the senior sister by roughly two years over Sunday.

Eliana Kalogeras age 19

Eliana, the youngest, is 19 in 2025. No conflicting ages for Eliana appear across the sources reviewed.

What this means: the age gap between the three sisters is tight — under five years total — which explains the tight-knit family dynamic visible in their content. The reporting lag on a few sites is a reminder that birth dates matter: Sunday’s May birthday means some databases refresh later in the year.

Why does Demitra call Sunday Kailea?

Kailea is Sunday’s first name

Sunday’s legal first name is Kailea. Her older sister Demitra uses this name in personal settings to distinguish between Sunday’s birth name and her public alias. The practice is referenced in Briefcurrent (media blog), which notes that the nickname “Sunday” itself may derive from the Greek word for the day of the week, though this origin has not been officially confirmed.

Nickname vs legal name dynamic

Demitra calling Sunday “Kailea” is a family shorthand, not a mystery. It mirrors a pattern common among siblings of public figures: using the legal name as a marker of intimacy. For context, the Wikitubia community wiki identifies all three sisters by their full names and notes that Sunday is the “middle sister.” No source suggests tension or confusion — just a straightforward name preference.

Is Sunday from the Kalogeras sisters dating anyone?

Current relationship status

Sunday Kalogeras has not publicly confirmed a boyfriend or dating relationship as of 2025. Occasional social media posts have included ambiguous mentions, but Briefcurrent and other secondary sources state that no verified partner has been identified. Her relationship status remains in the “unconfirmed” category — not denied, not confirmed.

Public information

The lack of an official confirmation is typical for creators who maintain boundaries around private life. Sunday’s Instagram account (@sundaykalogeras, 5 million followers) shows lifestyle content, fashion, and family clips, but no consistent romantic references.

The implication: for fans tracking relationship rumors, the evidence is insufficient to draw conclusions. Until Sunday or a family member explicitly addresses the topic, the default stance is “not confirmed.”

Timeline of Sunday Kalogeras’s rise

The timeline signal is clear: Sunday’s growth accelerated between 2020 and 2023, typical for creators who caught the algorithm tailwind during the pandemic. Her current follower count suggests sustained engagement rather than viral spikes.
