100 days ago from today was 09 Feb 2024, a Friday. Subtracting a number of days that spans over three months takes us beyond simple day-to-day subtraction into calculating across weeks and months, crucial for understanding fiscal calendars. Considerations include the day of the week, and the length of both May and April, alongside seasonal and calendar transitions. Since today is Sunday, the calculation could get a bit more complicated if you want to account for business days becuase it's the weekend. Given we're in the middle of of May, with 19 days left out of the 31, factoring in shifting weekends of that quarter becomes essential. For such extensive backward calculations, starting with week-by-week or month-by-month subtraction might offer clearer insights.
