About this tool
Build an experience certificate, relieving letter or service certificate with exact tenure in years, months and days.
Experience Letter Format Builder produces three HR documents that are routinely confused with each other: an experience certificate (what a future employer asks for), a relieving letter (which confirms the employee was relieved on a stated date and dues are settled), and a service certificate (a bare factual record of employment). It calculates the exact period of service as a calendar difference in years, months and days, borrowing from the real length of the preceding month rather than assuming 30. A validity checklist flags the letterhead, reference number, employee ID and authorised signatory that a usable document needs.

Calendar maths handles leap years and month-end joining dates, so 31 January to 1 March reads as one month and one day.
Switching the document type rewrites the title, the body and the checklist for what that document has to say.
Conduct wording is optional and ranges from no comment to a strong endorsement, so nothing is claimed that the employer cannot stand behind.
An experience certificate confirms the role held and the period of service and is what a future employer asks to see. A relieving letter confirms that the employee was formally relieved on a stated date and that dues and company property are settled — new employers often require it before confirming a joining date. Many employers issue both.
As a calendar difference between the joining date and the last working day, expressed in years, months and days. Days are borrowed from the actual length of the preceding month, not a flat 30, so 15 June 2019 to 3 August 2026 is 7 years, 1 month and 19 days.
Company letterhead with the registered address, a reference number, the date of issue, the employee's full name and ID, the designation held at the time of leaving, the exact period of service with both dates, and the signature, name, designation and seal of an authorised signatory. Missing the signatory designation is the most common reason a certificate gets sent back.
Several state Shops and Establishments Acts require an employer to issue a service certificate when an employee leaves, and comparable provisions exist for establishments covered by other labour legislation. The exact obligation depends on the Act applicable to the establishment, so check that Act or take professional advice rather than relying on a general rule.
