How to Change & Convert UK Dates to US in Excel

Bryan
Have you ever come across a scenario where your dates in Excel are in the wrong format?  Say you type in 01/05/2018 which actually means January 5, 2018 in the US but it shows as May 1, 2018.  It drives me nuts because the entire spreadsheet of dates is interpreted incorrectly by Excel.  That happens because your computer's region settings are in UK format and need to be changed to a US format. Thankfully, there is an easy way to change your Windows region & date settings so that the dates will be interpreted correctly by Excel! .

Key Takeaways

  • Understand the Date Formats – UK format is DD/MM/YYYY, while US format is MM/DD/YYYY, and Excel interprets them differently based on regional settings.

  • Use Text-to-Columns Tool – You can split and realign day, month, and year values using Text to Columns to fix misinterpreted dates.

  • Apply the DATE Function – Reconstruct proper dates with =DATE(YEAR, MONTH, DAY) when components are separated or incorrectly recognized.

  • Change Regional Settings – Update your system or Excel settings to US or UK locale to influence how Excel parses dates by default.

  • Convert with Power Query – For cleaner, large-scale conversions, use Power Query to transform UK-formatted text into actual US date format.

Frequently Asked Questions

Why is Excel misreading my UK dates?
Excel often defaults to the US date system, so a UK date like 13/05/2024 is not recognized because there’s no 13th month.

How do I convert a column of UK dates to US format manually?
Use =DATE(RIGHT(A1,4),MID(A1,4,2),LEFT(A1,2)) if your UK date is in DD/MM/YYYY as text.

Can I change the date format without changing the values?
Yes, right-click the cells, go to Format Cells > Date, and select the desired locale (English (United States) or English (United Kingdom)).

Is Power Query better for bulk date conversion?
Absolutely—Power Query can identify, split, and reformat thousands of dates reliably and with minimal manual work.

What happens if my dates are stored as text?
Excel won’t treat them as actual dates. You need to parse them using formulas or Power Query to convert them into date values Excel understands.
