The significance of Baby Ardern's birth date

New Zealand Prime Minister Jacinda Ardern has finally given birth to a baby girl, but the date she arrived - four days after her due date - tosses up some rather interesting details.

It has been widely reported that baby Ardern shares a birthday with Prince William, singer Lana Del Rey, and actor Chris Pratt.

Less well known is that she also celebrates alongside whistle-blower Edward Snowden and viral pop singer Rebecca Black.

June 21 is also the birthday of Benazir Bhutto, the only other Prime Minister to have ever given birth while in office. Ms Bhutto gave birth to her daughter in Pakistan in 1990.

Born just hours before Winter Solstice, Baby Ardern arrived right on the cusp of Gemini and Cancer season. Her rising sign is in Sagittarius and her moon sign is in Libra. 

According to Tarot.com, those born on the Gemini-Cancer cusp are fun, kind, and whimsical with huge hearts. They are curious, sentimental, and social individuals capable of strong relationships.

Other celebrities born on the Gemini-Cancer cusp between June 8 and 24 are Paul McCartney, Meryl Streep, Nicole Kidman, and Lionel Richie.

Having been born on a Thursday, Baby Ardern is said to have "far to go" in the traditional idiom. 'Thursday's Child' is also a Grammy-nominated David Bowie song from 1999.

In the Chinese Zodiac, being born in 2018 means Baby Arden belongs to the Year of the Dog. According to this, her lucky numbers will be 3, 4, and 9 and her lucky colours will be green, red, and purple. Her lucky flowers are said to be rose, oncidium, and cymbidium orchids.

Those born in the Year of the Dog are usually independent, sincere, loyal and decisive.
