Date & Time Calculation Tips
Working with Business Days

Remember to exclude holidays when calculating business days. Different countries and organizations observe different holidays.

Some organizations work Monday-Friday, others include Saturday or have different schedules. Adjust your calculations accordingly.
- Add buffer days for projects
When planning project timelines, add buffer days to account for unexpected delays or issues.
Date Calculation Best Practices

Decide whether to include both the start and end dates in your calculations and be consistent.

When working with international dates or events, be mindful of time zone differences that can affect your calculations.
