Happy New Year to you all and many thanks for continuing to visit 7puzzleblog.com.
It’s always weird writing the new date for the first time. I’ve repeated this question from last year as many of you will not have seen it, so here is a 2-part teaser to start off.
Although we are now in 2014, this question involves the four digits from last year, 2013:
- The year 2013 has four consecutive digits contained in its number. When is the next time a year will have this characteristic?
- 2013 also has four unique digits. When was the last time this happened?
