How this calculator works
A social media age limit stops accounts below a set age, so the time between now and that age is the window a young user actually has. Two hours a day sounds small, but multiplied by a year it becomes 730 hours, which is over 30 full days. The calculator multiplies the daily figure by the average length of a year, 365.25 days so leap years are included, then by the years left before the limit applies. If you are already at or past the limit, the years remaining show as zero, because the rule no longer binds you.
Formula
hours per year = (daily minutes / 60) x 365.25. Full days per year = hours per year / 24. Years until the limit = max(0, age limit - your age). Hours before the limit = hours per year x years until the limit.
Worked example
Two hours a day is 730.5 hours a year, or 30.4 full days. A 12 year old with a 16 year limit has four years left, so the habit accounts for 2,922 hours, about 122 full days, before the rule applies.

Frequently asked questions
What does an age limit actually change?
Rules differ by country. Some require parental consent below a set age, others ban accounts outright, and the details of enforcement decide how much time actually changes. The calculator measures the time, not the policy.
Is the daily figure the same as reported screen time?
Reported use is usually lower than measured use. Phone wellbeing dashboards track every session, so read your own dashboard figure rather than estimating from memory.
Does time spent messaging friends count?
Yes if it happens in a social app. Messaging inside the same app is part of the same screen time, even though it is social contact rather than passive scrolling.
Why show full days rather than just hours?
Hours are hard to picture. Thirty full days of a year is a clearer way to see the size of the habit, and it lets you compare it with holidays or a sport season.
