If you want to plant them this is what I do (in mid March though)
Fold a sheet of tabloid in half and roll it around a thin (i.e. 2" diameter) tall spray can, leaving a bit sticking out at the bottom.
Fold the bottom bit in under the can and pull it off and you will have a newspaper-pot.
Should be about 6" tall.
Fill with multipurpose compost, and loosely put your hand around the pots and drop them 4" onto the bench to get the compost to settle.
Put them in a gravel tray or similar (all bunched up tightly) and transfer the seedlings to them. You will have to be dexterous and gentle. If the root has grown through the kitchen paper you can tear the paper and plant paper-and-seedling together.
Plant out AS SOON as the first true leaf appears (that will be the third actual leaf, and it will look different to the first two). If you wait any longer the tap root will be coming out of the bottom of your paper pots and when you harvest your Parsnips they will look like gloves

In march it takes NO MORE than 3 weeks from putting the seedling into the pot before they need to be planted out
Use a bulb planter to make a deep planting hole and fill it with sifted soil - any stones will make the parsnips "fork" too). Tear of the top inch or so of newspaper when you plant so none sticks out of the ground (it acts as a wick and makes the paper underground dry out too)
Other people put the little seedlings straight into prepared soil outside (I've never tried that)
And sow some more at the time it says on the packet just-in-case these ones snuff it, or "bolt" during the Summer.
