Plan backward from the date that matters
Choose a target date, then turn the remaining time into manageable steps. Use days for short tasks, weeks for project milestones, and calendar months for longer plans. A recurring event automatically moves to its next occurrence after its date has passed.
How the calculation works
Day counts compare calendar dates and exclude the starting date. Whole weeks use groups of seven days; fortnights use fourteen. Months count complete calendar months, with any remaining days shown separately. Weekend counts count Saturdays strictly after the start date and on or before the target.
A useful next step
