It sounds like a simple math problem, right? You take one number, subtract the other, and move on with your day. But honestly, when people search for 2018 to 2025 how many years, they aren't usually just looking for a single digit. They're looking for a timeline of their lives. They're trying to figure out how a pre-pandemic world somehow bled into the mid-2020s while we were all looking the other way.
Seven.
That is the raw answer. If you subtract 2018 from 2025, you get 7. But if you are counting the years themselves—starting the clock on January 1, 2018, and ending it on December 31, 2025—you’re actually looking at an 8-year span of time. It’s that weird "inclusive vs. exclusive" counting glitch that trips everyone up during anniversary planning or lease agreements.
Why the math of 2018 to 2025 how many years feels so heavy
Time has felt... weird lately. Ask anyone who lived through the transition from 2019 to 2021.
Sociologists like Eviatar Zerubavel have long studied how humans perceive "time maps." We don't see years as equal blocks. We see them as landmarks. From 2018 to 2025, we haven't just moved seven spots on a calendar; we’ve navigated a complete overhaul of global culture, work-from-home shifts, and the rise of generative AI that wasn't even a whisper in the mainstream back in 2018.
Think about it. In 2018, the "Black Panther" movie was just hitting theaters, and the biggest tech news was often about the "notches" on new iPhones. Fast forward to 2025, and we are talking about spatial computing and deep-sea mineral mining.
Breaking down the 7-year gap
If we look at the calendar specifically:
2019 (1), 2020 (2), 2021 (3), 2022 (4), 2023 (5), 2024 (6), and 2025 (7).
But wait. If you include 2018 as the "starting" year, you add an eighth block. This is why businesses often struggle with contract lengths. If a contract starts on Jan 1, 2018, and expires on Jan 1, 2025, it has lasted exactly seven years. If it expires on Dec 31, 2025, it has lasted eight. Words matter.
The Leap Year Factor
You can't talk about the span of 2018 to 2025 how many years without mentioning the extra days. Our calendar isn't a perfect circle.
During this specific stretch, we encountered two leap years: 2020 and 2024. That means there are two "extra" days (February 29th) tucked into that seven-year gap.

Total days?
365 multiplied by 7, plus those 2 extra days.
That’s 2,557 days.
It sounds like a lot more when you put it that way, doesn't it? 2,557 days of habits, commutes, meals, and sleep.
The "Lost Time" Perception
There is a psychological phenomenon often discussed by researchers like Marc Wittmann, a psychologist at the Institute for Frontier Areas of Psychology and Mental Health. He notes that when our routines are disrupted, our "internal clock" gets messy.
The 2018 to 2025 stretch contains the "COVID gap." For many, 2020 to 2022 feels like one long, blurry year, while 2018 feels like a decade ago. If you feel like the math doesn't "feel" like seven years, you aren't crazy. It’s a documented cognitive bias where high-stress periods distort our memory of duration.
Career and Economic Shifts since 2018
In 2018, the federal minimum wage in the US was $7.25 (it still is, technically, at the federal level, though many states have moved on). The S&P 500 opened 2018 around 2,695. By early 2025, we’ve seen numbers that would have looked like typos back then.
The career trajectory of someone entering the workforce in 2018 vs. 2025 is night and day. In 2018, "remote work" was a perk for Silicon Valley elites or freelancers. By 2025, it's a standard negotiation point for a massive chunk of the global labor force.
Seven years is often the "itch" period. It’s the length of time many people stay at a job before burning out or seeking a total pivot. If you started a path in 2018, by 2025, you are likely a completely different professional.

What changed in the tech world?
Basically everything.
- Social Media: In 2018, TikTok was just starting to merge with Musical.ly. It wasn't the juggernaut it is today.
- AI: In 2018, "AI" meant Siri occasionally understanding your request for a timer. In 2025, it's writing code, generating video, and running logistics for Fortune 500 companies.
- EVs: Look at the road. In 2018, seeing a Tesla was a "spot the car" game. In 2025, almost every major manufacturer has a full electric lineup.
Practical Steps for Measuring Your Own 7-Year Cycle
If you are looking at the 2018 to 2025 how many years gap for personal reasons—maybe a statute of limitations, a credit report cleanup, or a personal milestone—here is how to handle the data:
- Check your inclusive dates. Always clarify if the "end" date is the start or end of 2025. This changes your calculation by 365 days.
- Account for the leap days. If you are calculating interest or daily rates, remember 2020 and 2024 had 366 days.
- Audit your documents. Passport renewals, driver’s licenses, and professional certifications often run on 5 or 10-year cycles. If you got yours in 2018, you’ve likely already passed a 5-year renewal (2023) and are heading toward that 10-year mark in 2028.
- Reflect on the "Seven Year Itch." Use this math as a prompt for a personal audit. Where were you in 2018? If the 2025 version of you hasn't changed, it might be time for a deliberate shift.
The distance between 2018 and 2025 is exactly 2,557 days (or 2,555 if you ignore the leap years, but why would you?). It's enough time for a child to go from kindergarten to the end of elementary school. It’s enough time for a startup to go from a garage to an IPO. Most importantly, it's enough time for you to have completely reinvented who you are.
The math is easy. The lived experience is what actually counts.
