If nobody wants to start the next 64 mio countdown thread, then with your permission, I’ll start it.
For beginners, I will explain that in some time the total number of postcards registered (=received) will reach 64 million. In the thread of this countdown, we need to make predictions about the time when it will happen and time to time to refine these predictions.
We have a counter of the current received postcards at the moment on the Postcrossing main page in the Postcrossing block in numbers and in the Received postcards line:
And some statistics by months are also here:
Then your intuition, or Excel, or the Crystal Magic Ball starts to work.
We are all in different time zones, so it is better please to indicate the date and time in UTC format:
So, my initial prediction is
03.11.21 16:09 (UTC).
