How Many Business Days Are in 23 Years Before Today?
The target date falls on a weekend (Saturday). The nearest working days are Friday, September 12, 2003 (before) and Monday, September 15, 2003 (after). There's no simple way to convert a multi-year span into a running business day count. What matters here is simply whether the target date itself falls on a weekday.
Leap Year Impact: This span crosses 6 leap years (2004, 2008, 2012, 2016, 2020, 2024), so it covers 8401 days rather than a flat 8395 (which would be 23 times 365). That extra day is also why the weekday shifts unpredictably going backward.

How to Calculate 23 Years Before Today Manually
To find this date by hand, subtract 23 from the current year and keep the month and day the same.
This only applies if today's date were February 29th, a leap day — subtracting years could land on a year that isn't itself a leap year, forcing the date to roll to February 28th or March 1st. Since today isn't February 29th, this doesn't apply here, but it's worth knowing if your own birthday or anniversary falls on that date.
