The day’s calculator is an efficient calculator developed to find the number of days between two dates, adding days to specific dates and subtracting days from a given date. This article will explore how this day’s calculator works, calculation formulas, practical examples, and a few frequently asked questions.

A day is the time it takes for the Earth to rotate once on its axis, which is about 24 hours. A day is divided into daytime and nighttime, based on whether your location is facing the Sun or not. Each day is made up of 24 hours, and every hour has 60 minutes.

How does this calculator work

Days between

To find the number of days between two given dates, subtract the earlier date from the later date. If the end date hasn’t reached the same month and day as the start date, make a slight adjustment to get the correct value.

Total Days = (End Date − Start Date) + Adjustment

For example: January 15, 2023 to March 10, 2023 = 54 days.

Adding days

Adding days to a given date helps you add a specific amount of days to the starting date. Also, this operation follows the same date format unless a new date moves into a new month or year.

New Date = Start Date + Number of Days

For example: December 31, 2023 + 2 days = January 2, 2024.

Subtracting days

Subtracting days from a date lowers a certain number of days from the start date. This function, like adding days to a given date, maintains the date format unless it needs to be changed, such as changing to a different month or year.

New Date = Start Date − Number of Days

For example: January 5, 2023 − 10 days = December 26, 2022.
