We’re not sure that the formula is intended for years beyond 2099. We’ve tried a few examples for years 2100 through 2199, and if one subtracts 3 instead of 1 before the last step, it works for the sample dates that we’ve tried, including March 3, 2147. But we’re not sure if it would apply to all dates in that yearly span.
Hi, Ana,
We’re not sure that the formula is intended for years beyond 2099. We’ve tried a few examples for years 2100 through 2199, and if one subtracts 3 instead of 1 before the last step, it works for the sample dates that we’ve tried, including March 3, 2147. But we’re not sure if it would apply to all dates in that yearly span.
Hope this helps!
