The more accurate response is: 7 years, 9 months and 22 days. This was calculated from December 31, 2018 until today.
2018 was 7 years ago because we are now in 2026.
2018 was 93 months ago because we’re currently in October 2026. Here's how to calculate this: each year has 12 months so, 7 x 12 = 84. Add the 9 months passed since the beginning of 2026 and you get, 84 + 9 = 93.
2018 was 407 weeks ago. The trick I like to use is to first calculate how many days have passed since 2018 and divide that number by 7 (days in a week). In short, 2852 / 7 = 407.43, but only the quotient is relevant here, 407.
2018 was 2852 days ago because today is October 23, 2026. Given that most years are at least 365 days long, we get 7 x 365 = 2555. The following step is to add the days passed since the beginning of this year, 2555 + 295 = 2850. The final step is to count the leap years. There were 2 leap years since 2018, which means we need to add 2 more days for a total of 2852.
While it might be a bit over the top, you can also calculate how many hours passed since 2018. Because we already know the number of days, it would be 24 x 2852 = 68448. Since it’s 11:11 AM at the moment, we have to add 11 (hours passed since midnight) to 68448. So 2018 was 68459 hours ago.
