How Long Is Your Favorite Pop Group's Birthday Season?

We're right in the middle of Fifth Harmony's birthday season -- the time between the initial member's birthday and the last's, without regard to birth year -- which lasts an incredibly short 38 days. That's right: the four members of Fifth Harmony all have birthdays within an incredibly short time period.


That tiny birthday season inspired me to answer the question: does any other pop sort come close to Fifth Harmony's 38-day birthday season? Here's what my investigation revealed, from longest to shortest birthday season.


Why Don't We


The gentlemen of Why Don't @we could be close, although their birthdays aren't at all. Daniel's birthday is on April 2 and Corbyn's is on November 25, with Zach, Jonah and Jack's birthdays in between. That's a birthday season span of 238 days.


Pentatonix


A cappella icons Pentatonix blend their voices perfectly and yes it could have something to do with how far apart their birthdays are. Their birthday season ranges from newest member Matt's birthday on February 11 to all-star beatboxer Kevin's birthday on October 5. Altogether, that's a birthday season of 237 days.


PRETTYMUCH


Maybe it's something about boy bands began in 2016 -- PRETTYMUCH's birthday season is essentially as long as Why Don't We's. It begins with Zion's birthday on June 29 and ends with Edwin's on February 12, for a grand total of 229 days.


5 Seconds of Summer


Though Ashton and Luke's birthdays are only nine days apart in July, Mikey's and Calum's are a long ways away. Between Ashton's birthday and July 7 and Calum's birthday on January 25, 5SOS has a birthday season of 203 days.


Little Mix


The Little Mix gals' birthdays are paired up nicely, although those pairs are far apart. With Jesy and Perrie celebrating on June 14 and July 10, and Leigh-Anne and Jade celebrating on October 4 and December 26, that's a birthday season total of 196 days.


DNCE


Joe Jonas might be close with his brothers, nevertheless his birthday isn't also close to his bandmates. He starts the DNCE birthday season on August 15 and yes it ends with Cole's birthday on February 22. Their birthday season span comes out to 192 days.


BTS


Despite being a huge order with seven members, BTS keeps their birthdays relatively close with each other. Beginning with Jungkook's birthday on September 1 and ending with Suga's on March 9, the males birthday season is wrapped up in 190 days.


One Direction


With or without Zayn, One Direction's birthday season doesn't change, since his birthday fell in the middle of the others'. From Liam's August 29 birthday to Harry's February 1 birthday, their birthday season lasts 157 days.


The Vamps


The Vamps' birthday season falls squarely into spring and summer, with Connor beginning it on March 15 and James closely in back of on April 30. At the tail end, Bradley's birthday is July 28 and Tristan's is August 15. Although with those two pairs of birthdays spaced out, The Vamps' birthday season is 154 days.


CNCO


The CNCO males may have been put with each other right after winning the competition television show La Banda, although fate may have had something to do with it considering how tight their birthdays are. Christopher's birthday is November 23 and Joel's is February 28, with Zabdiel, Erick and Richard filling up December and January. Altogether, that's a birthday season of 98 days.


Fifth Harmony


As it turns out, no pop groups hold a candle to Fifth Harmony's birthday season. It begins on May 31 with Normani's birthday, gets real hype in June for Dinah's and Lauren's birthday and ends on July 7 with Ally's birthday. That's just 38 days, even if excluding former member Camila. (Their birthday season becomes 127 days if including Camila's March 3 birthday).
