I want to know the answer to the following question:
When was the Calendar act enacted?
All the background I'm provided with is that "They can indicate that the start of the Julian year has been adjusted to start on 1 January (NS) even though contemporary documents use a different start of year (OS); or to indicate that a date conforms to the Julian calendar (OS), formerly in use in many countries, rather than the Gregorian calendar (NS).". Is that enough to answer the question?
