How many minutes are in 28 years?
By multiplication, this would be 14,726,880 minutes.
There are 1440 minutes per day. There are 365 days in a year, so 525,600 minutes in a year. So 28 years would be 14,716,800 minutes, except that 28 years will have 7 leap years, so add 7 x 1440 for those 7 extra days [10,080 minutes].
You reach the same value by multiplying the minutes per day by 365.25 (the Julian year) and then by 28 years.
However, by the "SI year" of exactly 31556926 seconds, the number of minutes in 28 years (multiplied by 28 and divided by 60) would be 14,726,565.47 minutes in 28 years.

When did we first start keeping time?
Long before modern humans evolved by watching the "movement" of the sun, moon, and stars. However this became much more important when humans settled down and began farming about 10000 years ago, to better determine the planting and harvest times. These were all easy to observe before electric lighting was developed.
In the middle ages it became more important to correctly determine the hours of the day so that people could attend church prayers and rituals.
In the industrial revolution and especially as shipping and railroads expanded accuracy of measuring time became very important.

Is it okay to tan 3 days after you get a tattoo?
Not at all. You want to wait about a good month after getting a tattoo before you go out in the sun to tan. Having a healing tattoo is a vulnerability out in the sun and it will do nothing but delay the healing time most likely. There is little chance of actual harm being done to your skin and body if you are not bathing in it for hours, but you should still avoid direct sunlight throughout the healing time. Also, once healed, excessive tanning will break down your tattoo and make the colors less vibrant over time as well.
