October 2016 – 5 Mondays, 5 Saturdays, 5 Sundays

It is perfectly true that October 2016 has 5 Mondays, 5 Saturdays, and 5 Sundays. However, such a combination is not at all remarkable and occurs far more often than once every 823 years. The last occurrence was in October 2011 while the next occurrence will take place in October 2022. In reality, any month that has 31 days will have three consecutive days that occur five times in the month. Such combinations are commonplace and occur each and every year. This meme is just an updated version of several earlier – and equally nonsensical – chain messages.

The last time such a combination occurred was in October 2011 :

And, it will next occur in October 2022 :

Furthermore, October in every single year will have three consecutive days that occur five times. In fact, any month that has 31 days will have three consecutive days that occur five times in the month. Such combinations are perfectly normal, perfectly predictable, and occur each and every year.

This message is just a revamped version of several earlier, and equally spurious, messages that featured other months and other years.
