Starting today, Monday February 17, 2025, we have 45 weeks left because we are currently in week number 8 of the year. This means we have 317 days left, 227 workdays left for the corporate folk, 7608 hours left, 1816 work hours including an hour lunch because we deserve it, and 456480 minutes, 27388800 seconds, and 3 quarters of the year left.
There are currently 45 work weeks left in 2025. The weeks themselves may not change but what does matter is the fiscal year. We are currently 51.65% through the quarter which means financial reporting, taxes, and EOY planning all become relevant. With the traditional work week being shorter unless you work weekends or get paid overtime, we currently have 317 days left in the 2025 fiscal year.
Solving for the number of weeks left this year is not as simple as it may seem. We recommend using a calculator like ours above to account for the little nuances of leap years, shortened months, and even holidays if you're looking for a fiscal calendar. Beyond a calculator, we can do it by hand which usually starts with an understanding week dates (see below). If you’re in North America, you probably haven’t worked much with this notation as it’s more common in European countries. Regarldess, let's dive into ways you can quickly calculate time until the end of the year in a few ways.
Foundational weeks conversion
Count the number of weeks
Once you’ve identified the week, each corresponding Monday will then denote the week. This will contain all 52 weeks and possibly week 53 for leap year.
Identifying specific dates through week numbering
A precise date using ISO week-numbering is similar to how we show a date with the addition of the weekday digit following this format: Year + week number, day number.
The Gregorian leap cycle has 97 leap days across 400 years. There are 20,871 weeks within those years with 71 years having an additional 53 weeks.
Week numbers are how we begin our calculation. The chart below is the updated ISO week numbers to calculate the change in year. Below the numbers are how to use this chart, identify which week refers to which date, and the logic behind it all.
