Q: Why do months have different end timestamps?

Months have between 28 and 31 days, so the end timestamp depends on the number of days in that particular month. February has 28 days (29 in leap years), while months like January and March have 31 days.

Q: How do timezones affect date boundaries?

Day boundaries differ by timezone because a "day" starts at midnight in each timezone. For example, midnight in New York (EST) is 05:00 UTC, so the day boundary timestamps will be different depending on which timezone you use.
