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 September 3. 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 August 21.

The only truly global conflict in history began when German troops crossed into Poland in September 1939.
The Second World War began twice, once in September 1939 for the countries of western Europe, and then again in February 1941 with the entrance of Japan and the United States of America. For those early months, long and bruising, Great Britain stood alone against almost every government from Norway to Spain.
