Common questions about 20 months ago
Does subtracting many months from a date during DST changes impact the time calculation? ▾
Subtracting a large number of months crosses multiple DST transitions, so while the calendar date adjusts easily, the exact time can shift by one hour due to DST changes in the target period.
How do large month subtractions handle end-of-month dates like January 31? ▾
When subtracting many months from an end-of-month date, if the target month has fewer days, the date defaults to that month's last day, such as moving from January 31 to November 30.
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.

Did You Know?
Calendar months vary in length from 28 to 31 days, which is why "one month ago" is not the same as "30 days ago." The mismatch grows over time: 12 months ago is always the same calendar date one year prior, whereas 365 days ago can differ by one day in a leap year. For precise financial and legal date calculations, always use calendar months rather than a fixed number of days.
