And many folk do not work during the day. 9-5 jobs aren't necessarily the norm anymore. Additionally, the time your packages are delivered is based upon your geographical location within the driver's route. You just happen to be in an area where the driver has to deliver earlier in the day in order to get his/her route finished. Others do get their stuff delivered in the evening.

As a word of advice, whenever possible when using Fedex, have it shipped via Home rather than Ground. Home's work week is Tuesday through Saturday, so you can arrange to have a Saturday delivery when you're home.
