About Refill Date Calculator (Formula)
The Refill Calculator is a simple tool that helps users determine when they should refill a container based on the last fill date and the number of days of supply they have. The calculator uses the following formula to calculate the next fill date:
nextFillDate = lastFillDate + (daysOfSupply x 86400000)
Where:
- last fill date: The date of the last fill in milliseconds since January 1, 1970 (epoch time)
- days of supply: The number of days of supply remaining before a refill is needed
- 86400000: The number of milliseconds in one day
The next fill date is then calculated by adding the number of days of supply to the last fill date in milliseconds. This value is then converted to a date format (yyyy-mm-dd) and displayed as the next fill date.
It’s important to note that this is a basic example, and you may need to customize it according to your needs and requirements.
