It is a question that sneaks up on you - usually somewhere around September, when the year feels both endless and almost gone. So how much of it is actually left? This covers how to work it out, why the number is worth having, and how to keep it in front of you instead of recalculating it every time you wonder.

Short version: divide the day of the year by 365 to get how much has passed; the rest is what is left. Or put a year progress widget on your home screen and never do the maths again.

How to work it out

A year has 365 days (366 in a leap year). To find how far through you are, take the current day number - how many days since 1 January - and divide by the total. As a rough guide:

End of March is about 25% through the year.
End of June is about 50%.
End of September is about 75%.
Early December is around 92%, with the last few weeks to go.

So by late September, roughly a quarter of the year is left. The exact figure shifts every day, which is precisely why doing it by hand gets old fast.

Why the number is worth having

A percentage does something a date on a calendar does not: it makes the passing of time visible. "October" is abstract; "78% of the year gone" lands differently. For some people it is motivation - a nudge that the goals set in January still have a clock on them. For others it is just a quiet bit of perspective. Either way, seeing it beats forgetting it until New Year's Eve.

How to keep it on your home screen, step by step

1. Install a year progress widget

Install Elapsed from Google Play. It is a home-screen widget that shows how far through the year you are, with no account or internet needed.

2. Add the widget to your home screen

Add the Elapsed widget to your home screen and the year bar starts filling right away, updating automatically as time passes. There is nothing to open and nothing to tap.

3. Glance at it whenever you unlock your phone

The percentage is there every time you look at your home screen, so you always know how much of the year is left without doing any maths - and the same widget can show the day, week and month too, if you want the smaller cycles alongside the big one.

The app behind this guide

Elapsed is my own Android home-screen widget, and it is what this guide describes. It shows progress bars for the day, week, month and year, each filling automatically as time passes - no tapping, no account, no internet, and no data collected. It runs entirely on your device with zero battery impact.

The free version includes the full widget with its default style - clean white dots on a dark background, monospace type. A one-time Pro unlock, with no subscription, opens up the customization: bar styles, independent colors, fonts, fine adjustments, row order, and the handcrafted presets like Arctic, Terminal, Sakura and Hacker.
