T24 Date Converter

Convert dates between all T24 formats, calculate offsets, find day differences, and browse common COB cycle dates — all in one place.

T24 date formats explained

T24 uses multiple date formats depending on the context. The most common is YYYYMMDD, used in OFS messages for fields like EFFECTIVE.DATE and VALUE.DATE. But you will also encounter DD MON YYYY in enquiry displays, *DDMONYYYY/ in internal T24 storage, and TODAY±N in batch job configurations and COB schedules.

Getting the format wrong is a common source of errors — an OFS message with a date in the wrong format will be rejected, and a COB job configured with the wrong date offset can process the wrong day's transactions. This converter handles all the standard T24 date formats so you do not have to remember the syntax for each one.

Date conversion example

Enter 20260425 (25 April 2026) into the converter and it will show you:

  • OFS format: 20260425
  • T24 display: 25 APR 2026
  • UK format: 25/04/2026
  • ISO format: 2026-04-25
  • T24 internal: *25APR2026/
  • T24 relative: TODAY-9 (if today is 4 May 2026)
  • Friendly: Saturday, 25 April 2026

You can also calculate offsets (e.g. +30 days from a date), find the difference between two dates, and look up common COB cycle dates like month-end or next Friday.

Frequently asked questions

What date format does T24 use?

T24 uses several date formats depending on the context. The primary format for OFS messages and data storage is YYYYMMDD (e.g. 20260425). Display formats use DD MON YYYY (e.g. 25 APR 2026). Internal T24 storage uses *DDMONYYYY/ (e.g. *25APR2026/). Batch and COB configurations often use TODAY±N (e.g. TODAY-1 for yesterday).

How do I convert a T24 date to a normal date?

If you have a date in YYYYMMDD format (e.g. 20260425), enter it into this converter and it will show you the equivalent in DD/MM/YYYY, DD MON YYYY, and other common formats. The converter also supports DD/MM/YYYY input, DD-MON-YYYY, and YYYY/MM/DD.

What does TODAY+N mean in T24?

TODAY+N is a relative date reference used in T24 batch jobs, COB schedules, and enquiry configurations. TODAY means the current system date, TODAY+1 means tomorrow, and TODAY-1 means yesterday. This converter can show you the absolute date for any TODAY±N offset.
