Seed-Time Ministries began in 1970, when a local grocer sponsored some Bible study programs on a small radio station in Tillamook, Oregon. Later the program was moved to Bakersfield, California and hosted by the Penners, under whose leadership it grew. Seed-Time's present teacher, Pastor Ashley Day, started off in a school of languages in London's West End. The Lord called him into the ministry when Billy Graham first visited London in 1954. In the rural areas of Cornwall, he preached in small pastorless churches for several years while working in a china clay mine to earn a living.

After immigrating to the United States in 1959, Pastor Day and his wife, Edna, first served in the Milwaukee Rescue Mission and then with Village Missions, where they pastored several churches in Oregon. In 1973, he became Chaplain at Stonecroft, the headquarters of the mission in Kansas City. The radio ministry was operated from that location and its first overseas broadcast began from HCJB in Quito, Ecuador. In 1975, the Days were called back to England, to minister at the Brookdale Evangelical Church in Devon.

In 1980, the Days returned to the United States to pastor the Coeur d'Alene Bible Church, in Idaho. Seed-Time Ministries was transferred to the church and was supported by the congregation as a missions outreach. Pastor Day served as Senior Pastor until December, 1998, when, upon his retirement from the full-time ministry, he became Pastor Emeritus. He continues to direct Seed-Time Ministries. The Days have five children.
