Why was it called the February Revolution even though it took place in March?

The revolution took place on March 8, 1917 but it is called the February revolution because of the Julian calendar that the Russians still used at that time. At that time, Russia had not switched from the Julian calendar to the new Gregorian calendar.

The Julian calendar was 11 days behind the Gregorian calendar, that is why the revolution is dated in the month of march but after the Bolshevic Revolution made the switch, the event was recalculated and converted under the new calendar and that the reason why the event appear to be in the following month.
