370 weeks ago from today was Friday March 17, 2017, a Friday. We use this type of calculation in everyday life for school dates, work, taxes, and even life milestones like passport updates and house closings. It might seem simple, but counting back the days is actually quite complex as we’ll need to solve for calendar days, weekends, leap years, and adjust all calculations based on how time shifts. If you’re traveling, time zone could even be a factor as could time in different cultures or even how we measure time. Let’s dive into how this impacts time and the world around us.

Calculating Days of the Week for Date
Counting backwards from day of the week is more challenging math than a percentage or ordinary fraction because you have to take into consideration seven days in a week, 28-31 days of a month, and 365 days in a year (not to mention leap year). But there’s a fun way to discover that X days ago is a Date. Of course, the fastest way to calculate the date is (obviously) to use the calculator. But for the math wiz on this site, or for the students looking to impress their teacher, you can land on X days being a Sunday all by using codes.
Each date has three parts: Day + Month + Year
To calculate the date, we will need to find the corresponding code number for each, divide by 7, and match our “code” to the day of the week.

Year Calculations
Calculating the year is difficult. Divide the last two digits of the year by four but forget the remainder. Then add the number by the last two digits of the year. If you’re going way back in time, you’ll have to add a few numbers based on centuries.
- 1700s dates +4
- 1800s dates +2
- 1900s dates +0
- 2000s dates +6
- 2010s dates +4
For simplicity, use the pattern below:
- 2018: 2
- 2019: 3
- 2020: 5
- 2021: 6
- 2022: 0
- 2023: 1
- 2024: 3
- 2025: 4
How to Calculate a Date
- Add the day + month + year
- Divide by 7
- Apply your remainder to the day of the week - Sunday being 0
Example: July 4, 2022 = 4 + 4 + 0 = 8
8/7 = 1 with remainder 1
Therefore, July 4, 2022 was a Monday.
