DMY to MDY Date Converter

Convert a calendar date written as DD/MM/YYYY into MM/DD/YYYY. For example, 14/02/2020 becomes 02/14/2020.

Use

In Open Flow, run with Value, such as 14/02/2020. In n8n, edit the value string at the start of Validate and format calendar date and run the workflow manually. Both formats return the converted string in data. No account or external service is required.

Use two digits for the day and month and four digits for the year. The workflow checks month lengths and Gregorian leap years. Invalid dates, extra text and other input formats stop the run. It does not guess the date convention, convert timezones or create a timestamp.

Changes to the source

• Make the source’s default MM/DD/YYYY output format explicit.
• Require the stated input format and a valid calendar date instead of accepting lenient parsing or returning an invalid-date string.
• Use the same calendar calculation in both formats without depending on the execution machine’s timezone.

Adapted from Date and Time calendar formatting workflow in Zie619/n8n-workflows. The source export does not identify a separate template author or license.

The collection’s MIT notice is pinned at a later revision. This is the collection notice at that revision; it does not establish a separate original template author’s license. Our changes are listed above; see repository licensing.
