No, they're not the same. 148 and a half months from today would be September 20, 2037, while 646 weeks from today would be September 21, 2037 - about a 1-day difference. This occurs because months vary in length (28-31 days) while weeks are consistently 7 days.
To calculate 646 weeks from today, just add 4,522 days to the current date. The result will be the same regardless of time zone because you're calculating based on the number of days, not the exact hour or minute.
Time zones only affect the specific time of day (like converting a 3 PM meeting to the correct time in different regions). But for a date alone, time zones donβt impact the result. So, once youβve added the days, that date will be the same worldwide.
