Sources & scope

- Expose the checkpoints. Intermediate rows, warnings and timeline events stay visible; the emphasized row identifies the primary checkpoint when one exists.

What to know before using the result.
Does the parental leave calculator determine legal eligibility?
No. It plans calendar dates only; eligibility, pay, job protection, notice and concurrent leave depend on the applicable program and employer policy.
How is the last leave day calculated?
The selected number of calendar weeks begins on the leave-start date, making the last leave day one day before the same weekday after that many weeks.
Can I choose whether the return date is the last leave day or the next day?
Yes. The return-date convention is explicit so the result matches the wording in the plan you are using.
