Introduction to Mainframe Date Formats

In computing, date formats are key. Introduction to Mainframe Date Formats looks at the various formats used in mainframes. These are special and require expertise.

Step 2	Add either 1900 or 2000 to two-digit year (‘YY’) to get four-digit year (‘YYYY’)
Step 3	Format month as ‘mm’
Step 4	Format day as ‘dd’
Step 5	Combine these three elements with ‘/’ separator symbol		DD/MM/YYYY
