Fundamentals of Data Analysis Count signups within a time range

19. Count signups within a time range

“Well, the hype is going down”, said Gessica, “I see fewer articles and tweets about Bindle, we should think about starting a marketing department. Let’s see how many users signed up for Bindle within the first week after the website’s launch.”

Finally, we can calculate how many signups Bindle had within the first week after launch. A couple of reminders:

  • Bindle’s website was launched on January 1, 2018
  • The format for date strings is YYYY-MM-DD (year-month-date), 2nd of March would be 2018-03-02
