How do you count 90 days of work?

Calculating 90 Days of Work: Calendar Days vs. Working Days

Understanding how to count 90 days of work can be trickier than it initially seems. The key distinction lies in whether the 90-day period refers to calendar days or working days. This difference can significantly impact deadlines, project timelines, and legal obligations.

Legally, a "90-day" period usually refers to 90 consecutive calendar days. This means counting every day on the calendar, including weekends and holidays. This straightforward calculation simply involves counting forward 90 days from the starting date. For example, if your 90-day period begins on a Tuesday, January 1st, you count forward 90 consecutive squares on the calendar, regardless of whether they represent weekdays or weekends. This method provides a definitive end date.

However, in other contexts, such as project management or internal company policies, "90 days of work" might imply 90 working days. This calculation excludes weekends and potentially holidays. Determining the end date in this scenario requires a more nuanced approach.

Here's how to calculate 90 working days:

• Identify your work week: Do you operate on a standard Monday-Friday schedule, or does your work week include Saturdays or other days?
• Account for holidays: List all official holidays that fall within the potential 90-day period. These days will be excluded from the count.
• Start counting: Begin with your start date and count forward, excluding weekends and identified holidays, until you reach 90 working days.

Using a calendar specifically designed for business or project management can be helpful for this calculation. Many online tools and software programs can also automatically calculate working days, simplifying the process.

The distinction between calendar days and working days is crucial. Misinterpreting the terminology can lead to missed deadlines, legal complications, or project delays. Always clarify which method of calculation applies in your specific situation. When in doubt, err on the side of caution and confirm the intended meaning with the relevant party, whether it be an employer, client, or legal representative. Being precise in your understanding of "90 days" will ensure accurate planning and avoid potential misunderstandings.
