- Central government employees are entitled to eight days of casual leave per calendar year under the CCS (Leave) Rules 1972, and casual leave cannot be carried over to the next year
- A leave letter should follow the standard business letter format in full block or modified block style, stay within one page, and clearly state the reason and the exact leave dates.
What Is a Leave Letter?
A leave letter is a short formal request asking your employer, principal, or manager for approved time away from work or class. It states who you are, the reason for your absence, the exact dates, and how you can be reached, so the organisation can plan around your leave.
A leave letter and a leave application mean the same thing. Offices tend to say leave letter, while schools and colleges often say leave application, but both are formal documents that create a written record of your absence and give the person in charge the details they need to approve it.
How Do You Write a Leave Letter?
To write a leave letter, address the right authority, add the date, and open with a clear subject line. State the reason briefly, mention the start and end dates, confirm the total days, and offer handover or contact details. Close politely, then sign with your name and designation.
- Write your name, designation, and the date at the top.
- Address the letter to your manager, principal, or the relevant authority.
- Add a short, clear subject line such as Application for Casual Leave.
- State the reason for your leave in one or two sentences.
- Mention the exact start and end dates and the total number of days.
- Offer a handover plan or a contact number for urgent matters.
- Close with a polite line, then sign with your name and designation.
What Is the Correct Leave Letter Format?
A standard leave letter follows the business letter format: sender details and date, the receiver name and designation, a subject line, a formal salutation, the body stating reason and dates, a courteous closing, and your signature. Full block and modified block are the two accepted layouts used across offices.
In full block format every element starts at the left margin. In modified block format the date, closing, and signature begin near the horizontal centre of the page while the rest stays left aligned. Keep the tone polite and professional, avoid casual language, and limit the letter to a single page.

What Are the Rules for Casual and Maternity Leave?
Leave entitlements depend on your employer and applicable law. Under the CCS (Leave) Rules 1972, central government employees receive eight days of casual leave each calendar year, which cannot be carried forward. Maternity leave for eligible women workers was raised to twenty-six weeks under the Maternity Benefit (Amendment) Act, 2017.
Private companies set their own leave policies, so always check your offer letter or employee handbook before you apply. When you cite a specific entitlement in your leave letter, keep it accurate, mention the leave type by name, and attach any proof your organisation asks for, such as a medical certificate.
Formal Letter Format and ExamplesRead →How Can You Avoid Common Leave Letter Mistakes?
Avoid vague reasons, missing dates, and an over-casual tone. Keep the letter to a single page, use polite and professional language, and proofread for spelling and grammar errors.

- State a genuine, specific reason rather than a vague excuse.
- Always include the exact start date, end date, and total days.
- Keep the language formal and courteous, never casual.
- Attach a medical certificate or other proof when it is needed.
- Proofread the letter for spelling, grammar, and punctuation before sending.
