Time planning workflow
Calculate durations, timestamps, time units, business days, work hours, and media timing before sharing schedules.
Use this workflow when a plan mixes elapsed time, calendar dates, business days, timestamps, work hours, or media runtime and the assumptions need to be visible.
Public tools in this workflow are designed for browser-side processing unless a specific tool page states otherwise. Review each tool page before entering sensitive data. Review data handling.
