Common questions about 16 months ago
How many business hours roughly correspond to N months ago for large N? ▾
For large N months ago, approximate business hours by multiplying N by the average business days per month (~21) and then by daily business hours (typically 8), adjusting for holidays if precise calculation is needed.
Is subtracting N months a better way to measure long past periods than using days or years? ▾
Subtracting N months provides a more precise measure for long past periods than years alone, as it accounts for varying month lengths, whereas days offer finer granularity but can be less intuitive for calendar-based planning.
How do you calculate the date N months ago when N is a large number? ▾
To find the date N months ago for a large N, subtract the months one by one from the current date, adjusting the year as needed, and handle cases where the target month has fewer days than the current date.
If I look back several years in months, how does that affect the day of the week? ▾
Looking back a large number of months, spanning multiple years, the weekday shifts according to the total days elapsed, accounting for leap years, so the day of the week may differ from the original date.
