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 24. 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 March 11.

John Harrison’s Marine Chronometer

When Harrison won the Longitude Prize, fair and square, Parliament wouldn’t pay up.

Yorkshireman John Harrison was a carpenter by trade, but he taught himself clockmaking to such a high standard that he came to the attention of the Astronomer Royal, Edmund Halley.
