It is a peculiarity of knitters that they chronically underestimate the amount of time it takes to knit something. Birthday on Saturday? No problem. Socks are small. Never mind that the average sock knit out of sock-weight yarn contains about 17,000 stitches. Never mind that you need two of them. (That's 34,000 stitches, for anybody keeping track.) Socks are only physically small. By stitch count, they are immense.
