FAQ
Key questions answered
Does this calculator count whole weeks only?
Yes. It focuses on whole weeks so the result is easier to use in planning and scheduling.
What if I enter the dates in reverse order?
The calculator still measures the gap between the two dates, so the order does not break the result.
Are weekends or holidays removed?
No. It measures calendar time, not business days or working weeks.
Can I use it for notice periods or project plans?
Yes. It is useful whenever you need a clean weekly view of a date range.
Does it handle leap years?
Yes. It uses real calendar dates, so long spans still reflect the true elapsed time.
Why compare in weeks instead of days?
Weeks are easier to scan when you are planning milestones, routines, or recurring work.
When should I use a day calculator instead?
Use a day-specific tool when you need exact day counts rather than a broader weekly summary.
