Lida, the gentle months for sailing

The heathen English called both June and July Lida, meaning gentle or fit for sailing, because the breezes were mild and the seas could be sailed in both. Bede added that in a year of thirteen moons they put the extra month into summer, so that three months were called Lida and the year was called Thrilidi. This is his account of the old English year, not a Christian custom.
