Here’s the geeky part: the rate of change isn’t constant. In London, for example, sunrise jumps forward by about 2.5 minutes per day by late February. In New York, it’s similar—around 2.3 minutes daily. That’s nearly 17 minutes of extra morning light per week.
Why does this matter? Because your circadian rhythm is basically a drama queen that craves morning photons. When you wake up in darkness, your brain produces melatonin like it’s still midnight. When you see the first sliver of dawn, it signals your body to go.
Instagram meme culture has given this phenomenon its own vibe: “It’s getting light at 6:45 a.m. and I’m emotionally unprepared but ready.” Honestly, there’s a reason why seasonal affective disorder lifts in February. It’s not just the date—it’s the return of morning.
A timeline you can actually feel
Here’s a rough cheat sheet for mid-latitudes (think London, New York, Seattle, Paris):
Late January: Sunrise around 7:45 a.m. The first 10–15 minutes of twilight appear by 7:15 a.m. You’ll notice it if you’re a dog walker or an early commuter.
Mid-February: Sunrise jumps to about 7:15 a.m. The sky starts brightening around 6:45 a.m. This is when your morning run goes from “I can’t see the puddle” to “Oh hey, that tree has buds.”
When Do The Mornings Start Getting Lighter?
Early March: Sunrise before 6:45 a.m. You can now drink your coffee by actual daylight. This is the moment you start believing in spring again.
