Entering Values
The calculator includes input fields where you must enter the necessary values. These values are not saved, so you will need to re-enter them each time you reload the page.
Guidelines for Entering Data
Follow these best practices for accurate calculations:
Format Correctly: Ensure the start date and time follow the correct format (YYYY-MM-DD for dates, HH:MM for time).
Use Positive and Negative Values: Enter positive values to add time and negative values to subtract.
Leave Unused Fields Empty: If a field is not needed, leave it blank or set it to zero.
Check for Leap Years: When dealing with February, consider leap years to avoid errors.
24-Hour Format: Enter time in a 24-hour format to prevent AM/PM confusion.
Verify Time Zones: If working with multiple locations, account for time zone differences.
Handle Large Values Carefully: Adding large numbers, like 1000 days, may shift the date significantly.
