Start Date and Notice Period Calculator for Job Applications

Calculate an honest earliest start date from an offer or notice date, notice-period length, weekends, and a personal buffer. Free, private, and no signup.

Reviewed By Jobsistant
Calculate from your real constraint

Nothing is uploaded. The calculator counts weekends only as instructed; it does not guess public holidays or contract terms.

Your start date will appear here.

Use a planning date for an estimate, or a confirmed offer/notice date for a firmer answer.

Method

What the calculator includes—and what it cannot know.

The calculation begins with the date you choose, adds the notice period using your selected counting method, adds a calendar-day buffer, and optionally moves a weekend result to Monday. It never assumes that “two weeks” is the rule for your job.

Your employment agreement, collective agreement, employer policy, and local law can define when notice begins and whether holidays, leave, payment in lieu, or garden leave change the result. Acas, the United Kingdom's official workplace-advice service, defines a notice period as the time an employee remains employed after resigning and recommends checking the employment contract or written particulars. Read the Acas notice-period guidance.

Do not resign from a planning estimate.

If you do not have a written offer, choose “possible future offer date” and use the conditional wording. A calculator result is not an instruction to give notice.

Application wording

Use a commitment you can actually keep.

If the field accepts only a date, enter the earliest date supported by your real constraints. If it accepts text and an offer is not final, “approximately two weeks after accepting a written offer, subject to my contractual notice period” is safer than promising a calendar date that depends on an unconfirmed offer.

For more scenarios—including students, relocation, planned leave, and “immediately”—use the date available to start guide.

Privacy

Your dates stay in this browser.

The calculation runs locally. Jobsistant does not receive the dates or notice period you enter. With analytics consent, the site may record that a calculation completed, but not any field value or the resulting date.

Save the rule

Save your notice period once. Confirm the date each time.

Store your notice period in Jobsistant and it fills availability questions from it on every application, flagged for you to check, because the right start date depends on each offer. The rest of the form fills from your profile.
