The spreadsheet shows the best times for planting many of the common vegetable crops grown in the Prince William County portion of the Virginia Piedmont. The planting dates are for planting out into the garden. For most crops, this means when seeds are planted. For crops with asteriks* this is the date when seedlings are transplanted outside into garden beds. The calendar below is for Zone 7 which encompasses all of Prince William County, Manassas, and Manassas Park. The link below is for all of Virginia if you are interested.
