Notice Period Calculator
About This Calculator
The notice period calculator works out the date a notice period ends, counting from the day notice is given. Enter that date and the length of the notice — 30, 60, or 90 days are common — and it returns the end date, the weekday it falls on, and how many days are left until then.
Notice periods come up when leaving or ending a job, terminating a tenancy or rolling contract, cancelling a subscription with a cooling-off window, or giving contractual notice of any kind. The length is usually written as a number of days from the notice date, and the exact end date matters: it can decide your last working day, the final month of rent, or the last billing cycle you are liable for.
By default the calculator counts calendar days, which is how most contractual notice periods are measured, but you can switch to business days if your agreement is written in working days. Enter the notice date — it defaults to today — and the tool counts the period for you across month ends, so you do not have to.
The result shows how many days remain from today until the notice ends, and flags the date clearly if it has already passed. Everything is computed privately in your browser in a timezone-safe way, so the same inputs always give the same end date.
This is a scheduling tool, not legal advice — always check the exact wording of your contract, which may define when notice "starts" (for example, the next full month) differently. To count the days between two dates you already know, use the days between dates calculator; to add a period to a date more generally, the add days to date calculator does that.
How It Works
- Enter a start date (defaults to today).
- Enter the number of days and pick calendar or business days.
- Click “Find the deadline”.
- See the deadline date and how long is left.
Formula & Methodology
The result is worked out as follows:
Deadline = start + N days (calendar or business); days left = deadline − today
The notice end date is the notice date plus the notice length in days (calendar days by default, or business days if selected). Days left is the whole-day gap from today to that date. The tool does not apply contract-specific rules about when a notice period formally begins.
