Two-Digit Year Handling in Windows and Project

Q: Why are my Project dates shifted by a century?
A: Windows interprets two-digit years 00–29 as 2000–2029 and 30–99 as 1930–1999. So, a date like 30/01/30 may appear as 1930 instead of 2030.

Q: How can I prevent this?
A: Use one or more of these methods:

1. In Project: File » Options » General » Date format → select a format with a four-digit year. Do this before importing to @RISK.

2. Windows Short Date: Control Panel » Region » Formats → choose a short date format with a four-digit year.

3. Two-Digit Year Range: Control Panel » Region » Additional settings » Date tab → adjust “When a two-digit year is entered, interpret it as a year between” to cover your project dates (e.g., 1950–2049).

Tip: Choose a range comfortably beyond your latest project end date to avoid misinterpretation during simulations.
