To convert days to weeks, divide the number of days by 7 because 1 week = 7 days.
Example:
For partial weeks, the decimal shows the extra time.
A day is 1/7 of a week. That equals 0.142857 weeks (repeating). This conversion helps when you need to change short time spans from days to weeks.
Divide the number of days by 7.
A standard week has 7 days. This stays the same in all months and years.
Multiply the number of weeks by 7.
Yes. 14 days = 2 weeks because 14 ÷ 7 = 2. The same rule works for any number of days.
No. 10 days is 1 week and 3 days. In weeks, that is 10 ÷ 7 = 1.4286 weeks (rounded).
30 days ÷ 7 = 4.2857 weeks (rounded). That’s 4 weeks and 2 days.
365 days ÷ 7 = 52.142857 weeks. That’s 52 weeks and 1 day.
Months don’t have a fixed number of weeks. Most months have 28 to 31 days, which equals:
4 weeks = 28 days, but most months have 30 or 31 days. So 1 month is often longer than 4 weeks.
Use division by 7 to get both parts.
Example: 25 days
25 ÷ 7 = 3 weeks with 4 days left, so 25 days = 3 weeks 4 days.
Use decimals when you need a precise value, like schedules or billing.
Example: 9 days ÷ 7 = 1.2857 weeks.
For quick use, you can round to 1.29 weeks.
A week still equals 7 days, even if you only mean workdays. If you mean business days, you may need a different count since weekends are often excluded.
In many workplaces, 1 business week = 5 business days.
So 10 business days = 2 business weeks. This is different from calendar weeks.
For a fast estimate, remember:
This works well for planning and rough timelines.
