Sunday’s date is a rare palindrome that hasn’t happened in over 900 years

“We are so lucky to have such a special palindrome date occurring in our lifetime because it’s so rare,” Inan told USA TODAY Saturday.
For starters, it’s an eight-digit palindrome: 02022020. Many palindrome dates are only symmetrical if you write the date with seven digits (1-10-2011) — or in some cases even fewer (9-10-19).
But even more rare, according to Inan, is that Sunday’s date is an international palindrome: It works whether you write the date as “Month/Day/Year” or “Day/Month/Year,” as many countries do.
Inan calls such dates “ubiquitous palindromes,” and there won’t be another one for 101 years. After that, you’ll have to wait until March 3, 3030.
According to Inan’s calculations, the last such palindrome date to occur was 11/11/1111 – more than 900 years ago.
For years, Inan has been crunching numbers using a basic calculator and a pad of paper to find unique patterns  in dates.
“I advocate for these things because they’re so valuable for STEM education,” he said.
It’s an accessible kind of puzzle that he has used to engage students and get people talking about math.

Andre Ayew headed out of Swansea?

The future of Swansea City forward André Ayew is growing even more uncertain by the day, with interested clubs on standby after speculation concerning his possible availability. The Ghana International leads the charts for the Welsh side, with 11 goals in all competitions so far this season. With Swansea reportedly experiencing some financial instability following their relegation from the Premier League in 2018, Ayew is one of the names that have popped up on the exit list, due to his very high wages. The likes of Daniel James and Oli McBurnie have all left during that period, together with Jordan Ayew and Wilfried Bony among others have helped to significantly lower the wage bill. Tottenham Hotspurs and Championship leaders Leeds United have been identified as front runners for the Ghana international’s signature. Ayew rejoined Swansea from West Ham United in January 2018, then joined Turkish side Fernerbahce on loan for the 2018/2019 season, before returning to the We...
