Remarks upon the solar and the lunar years, the cycle of 19 years, commonly called the golden number, the epact, and a method of finding the time of Easter, as it is now observed in most parts of Europe

"Remarks upon the solar and the lunar years, the cycle of 19 years, commonly called the golden number, the epact, and a method of finding the time of Easter, as it is now observed in most parts of Europe" by George Parker Macclesfield is a scientific exploration presented as a letter, which investigates the intricate dance between solar and lunar calendars and how it all connects to finding Easter. Aimed at the President of the Royal Society, the writing carefully walks through how to figure out dates using calendars focusing on the math behind solar and lunar years, discussing the significance of the 19-year lunar cycle and explaining calendar differences to get to the correct date for religious purposes. Adjustments to the calendar's Golden Numbers are suggested to keep events in sync with what’s actually happening in the sky, making sure astronomical events and calendar dates line up. This provides a new way to approach timekeeping that has major implications for how both scientists and churches understood keeping time in Europe.
