How to Calculate Your Notice Period
The complete guide to working out your notice period — formula, calendar vs working days, and real examples for India and UK employees.
Quick Answer: The Notice Period Formula
Last Working Day = Resignation Date + Notice Period Days | Include weekends & holidays unless your contract says "working days"
What is a Notice Period?
A notice period is the length of time an employee must continue working after formally resigning — or that an employer must give before terminating an employee. It is usually set out in the employment contract or company policy and provides both parties time to prepare for the transition.
During the notice period, the employee continues to receive full salary and benefits, is expected to fulfil their duties professionally, and typically assists with knowledge transfer and handover documentation. The employer uses this time to begin the recruitment process or arrange internal cover.
Notice periods vary by seniority, industry, and geography. In India, 30 days is the most common notice period for mid-level professionals. In the UK, contractual notice for standard roles is typically 1 month, while senior positions often carry 3 months.

How Notice Periods Are Calculated
The calculation has three inputs: your resignation date, your notice period length, and whether your contract counts calendar days or working days.
Find your notice period length
Check your employment contract, offer letter, or HR policy. It will state the length in days, weeks, or months. Convert to days if needed: 1 month ≈ 30 days, 2 months = 60 days, 3 months = 90 days.
Identify your resignation date
This is the date you formally hand in your resignation — the date on your resignation letter or the date your manager/HR accepts it. This is day zero; it is not counted as part of the notice period.
Add the notice period days
Add the number of notice days to your resignation date. The resulting date is your last working day. Unless your contract specifies "working days", count every calendar day including weekends and public holidays.

Calendar Days vs Working Days
This is the most common source of confusion when calculating notice periods. The difference can shift your last working day by several days.
Calendar Days
- Counts every day including weekends
- Public holidays are included
- Most common — used by default if contract just says "30 days"
- 30 days from 1 Jan → 31 Jan
Working Days
- Only counts Mon–Fri
- Weekends and bank holidays excluded
- Less common — only if contract explicitly says "working days"
- 30 working days from 1 Jan → approx 12 Feb
Rule of thumb
If your contract says "30 days" — use calendar days. If it says "30 working days" — exclude weekends. When in doubt, ask HR to confirm in writing. The Notice Period Calculator uses calendar days by default, which matches the majority of employment contracts.
Notice Period Examples
Real calculations for 1, 2, and 3 month notice periods showing how month lengths affect the last working day.
1 Month Notice Period Examples (30 Days)
A 1 month notice period is typically 30 calendar days. Because calendar months have different lengths, the end date shifts depending on when you resign. Use the 1 Month Notice Period Calculator for the exact date.
January Resignation
February Resignation
Feb has 28 days — spills into March.
June Resignation
2 Month Notice Period Examples (60 Days)
A 2 month notice period equals 60 calendar days. Common for senior professionals and specialised roles in India. Because it spans two months, the end date can land in a third calendar month.
March Resignation
June Resignation
November Resignation
3 Month Notice Period Examples (90 Days)
A 3 month notice period is 90 calendar days. Standard for directors, VPs, heads of department, and C-suite roles. The 90-day window gives organisations sufficient time for senior hiring and leadership handover.

How to Work Out Notice Period in India
In India, notice periods are governed by the employment contract rather than a single national law. Most IT companies, banks, consultancies, and corporates specify the notice period in the offer letter or appointment letter. The most common notice periods in India are:
15 Days (Probation / Junior)
Common during probation and for junior or support-level roles. The 15-day notice applies only during the probation period — once confirmed, the full notice period takes effect.
30 Days (Mid-level — Most Common)
Standard for software engineers, analysts, team leads, and mid-level managers across IT, BFSI, and consulting. 30 calendar days is the default unless the contract specifies otherwise.
60 Days (Senior Roles)
Required for senior engineers, project managers, and senior consultants. The extended period allows time to hire or transition a replacement for a more complex role.
90 Days (Executive / Director)
Mandatory for directors, VPs, heads of department, and C-suite roles. Some contracts allow notice buy-out where the employee pays the equivalent salary for the remaining days.
Notice Buy-Out in India
Many Indian companies allow employees to "buy out" their remaining notice period by paying the equivalent days' salary. For example, if you have 45 days remaining on a 60-day notice and your company allows buy-out, you pay 45 days' salary to exit early. Always check your contract — not all companies offer this option, and some require management approval.
How to Work Out Notice Period in the UK
In the UK, notice periods are governed by both statutory minimums set by law and contractual notice periods agreed in the employment contract. Your contractual notice is almost always what matters — it is typically longer than the statutory minimum.
UK Statutory Minimum Notice
Under 1 month
No statutory notice
1 month – 2 years
1 week minimum
2 – 12 years
1 week per year
12+ years
12 weeks maximum
Most UK employers set contractual notice periods that exceed the statutory minimum. Standard roles typically carry 1 month (30 days) contractual notice; senior and director-level roles commonly require 3 months (90 days).
UK Example 1 — Statutory (4 yrs service)
UK Example 2 — Contractual 1 month
UK Example 3 — Contractual 3 months
Garden Leave & PILON in the UK
Garden Leave
The employer keeps you on full pay but asks you not to come in or work. You are still employed and bound by your contract terms (including non-compete clauses) for the duration.
PILON (Pay In Lieu Of Notice)
The employer pays your full salary for the remaining notice period and releases you immediately. Your employment ends on the PILON date, not the original last working day.
Common Mistakes When Calculating Notice Periods
Avoid these errors to ensure your resignation is clean and your last working day is accurate.
Counting the resignation day as Day 1
Your resignation date is day zero — not counted. The notice period starts the day after. Resign on 1 June with 30 days notice → last day is 1 July, not 30 June.
Skipping weekends from the count
Unless your contract says "working days", weekends and public holidays are included in the count. Most contracts simply say "30 days" — that means calendar days.
Assuming "1 month" is always 30 days
Some contracts say "1 calendar month" which means the same date in the following month — not exactly 30 days. Resign on 31 Jan → last day is 28 Feb (end of the calendar month). Check the exact wording.
Applying post-confirmation notice during probation
Probation notice periods are much shorter — typically 7–15 days in India and 1 week in the UK. The full 30/60/90-day notice only applies after you are confirmed as a permanent employee.
Not confirming verbal agreements in writing
If a manager verbally agrees to release you early, get it confirmed in writing from HR. Verbal agreements can be disputed during full-and-final settlement, affecting your relieving letter and salary clearance.
Leaving without completing notice
Abandoning your notice period without consent can result in salary deductions, a withheld relieving letter, and complications in background checks at your next employer.
