The table below shows the number of days per 1 duration unit in each case of the number of working days. Please note extra holidays do NOT affect the meaning of the duration units.
Number of working days | 7days | 6days | 5days | 4days | 3days | 2days | 1day |
---|---|---|---|---|---|---|---|
1 Week equals | 7days | 6days | 5days | 4days | 3days | 2days | 1day |
1 Month equals | 30days | 25days | 20days | 16days | 12days | 8days | 4days |
1 Quarter equals the number of days in 3 months. And 1 Year equals the number of days in 12 months.
Example
Your Gantt chart has 5 working days as Monday, Tuesday, Wednesday, Thursday, and Friday like the image below.
In this case,
8 hours equals 1 day.
1 week equals 5 days.
1 month equals 20 days.
1 quarter equals 60 days (20 days * 3 months).
1 year equals 240 days (20 days * 12 months).
