February comes from Februus
The name February comes from the Roman God Februus. Februa in Roman language also signifies the festival of purification that was celebrated in Rome during this month.
Why does February have only 28 days?
Julius Caesar who ruled Rome around 40 CE introduced the Julian Calendar.
Julius Caesar wanted to make his name not just popular but eternal.
Towards this purpose, he included his name Julius as a month in the calendar and thus came July, bearing his name. He also ensured that the month with his name had the maximum days and hence July has 31 days.
His successor Augustus Caesar, not wanting to be left behind, also wanted his name in history. He added his name to the following month and called it August. As he did not want his month August to be inferior to Julius in any way, he ensured that his month too had 31 days.
February to pluck
From where did Julius and Augustus pick their additional day from?
The month of February was there for them to pluck out the days from and add to their months.
