Read the passage from The Time Traveler's Guide to Elizabethan England.If you want to know which years are a good time to visit and which years to avoid, the following is a guide to the extremes. The years of greatest plenty—i.e., those in which the price of grain is 20 percent or more below the average—are 1564, 1566, 1569–71, 1583–84, 1587–88, 1592–93, and 1602, the very best being 1592 and 1593, when grain prices are just 56 percent and 65 percent of the average.
