Probation End Date
Free Probation End Date calculator with clear step-by-step results.
About Probation End Date
Adds the probation period and any extension to the start date using calendar months, so the end date lands on the same day of the month rather than drifting as a fixed day count would. Review dates are then spaced at the interval set out in the contract.
Formulas
End date
End = start date + (probation months + extension months) calendar months
Review count
Reviews = floor(total days / (review interval weeks x 7))

Assumptions and limits
- The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to whole numbers, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
- Not legal advice. Probationary periods, permitted extensions, notice entitlements and accrual of statutory employment rights are governed by law and contract, and vary by jurisdiction.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions
Can probation be extended indefinitely?
No. Employment law in most jurisdictions limits probation length or requires objective justification for extension, and statutory rights often accrue regardless of probationary status.
Does probation affect notice periods?
Frequently there is a shorter contractual notice period during probation, but statutory minimum notice and protection against unlawful discrimination still apply from day one.
