Time management well spent

My company is a family business and I serve as the marketing manager for their 3 different businesses, this helps me tremendously, with shipping, budgets and planning. Id like it to work with my calendar to show end date and start date events and options to skip major holidays and custom calendar entries. Perhaps smaller and larger increments of time, like hours and years. Not only is this useful for work but also other curiosities of time while off duty.
