We mark certain days of the year with ‘On This Day’ posts, recalling events associated with them.
Our events are grouped under two calendars. The Gregorian ‘New Style’ (NS) is the worldwide calendar first issued at Rome in 1582. On that calendar, today is March 13. The Julian ‘Old Style’ (OS), also issued at Rome but in 46 BC, was used in Roman Britain and then in England from Anglo-Saxon times until 1752. It is still used today by roughly 100 million Orthodox Christians worldwide. On that calendar, today is February 28.

Sir William Herschel not only discovered Uranus and infrared radiation, but composed two dozen symphonies as well.
William Herschel (1738-1822) came to Britain from Hanover hoping to avoid war with France. He became not only one of the country’s greatest astronomers, but also one of its most prolific composers, and his son John was, like William, knighted for services to astronomy.
