January 21st would be 31 days after December 21. 4 weeks is 28 days (7 * 4 = 28). So 4 weeks after December 21 is January 19.

no it depends on the month. 4 weeks = 28 days. so certain months with 28 day. December has 31 days, not 28 so it is actually 4 weeks and 3 days long. This means that exactly 4 weeks later will not be January 21st though it would be exactly 1 month later.

A month is roughly a bit longer than 4 weeks (28 days).
Months such as Jan, March, May, July, Aug, Oct and Dec have 31 days in a month whereas April, June, Sept and Nov have 30 days. February is a special with only 28 days a month but 29 during a leap year (ie. every 4 years)
So if something special happened on Dec 21, Jan 21 would be a month later rather than 4 weeks.

A month is 4 weeks plus 2-3 days, hence if something happened a month later it would be January 21st. If you look at your calender 4 weeks from Dec. 21st would be Jan. 18th

A month is the time from the date in one month to the same date in another, so from December 21st to January 21st would be a month. Otherwise, there wouldn't be 52 weeks in a year, there'd only be 48.

You must count the days to calculate the exact date of one month later.
