Then, there’s the countryside, with enough outdoor activities to fill another trip.
To get the most from your time in Uruguay, it makes sense to learn your options and plan ahead...
In this case, the Sunday of week 52 would be day number 3 52*7=367, i.e.
only the last 367-365=2 days of the W52 reach into the next year and consequently, even a worst case year like 1999 has a week W52 including the days 1999-12-27 to 2000-01-02. Both day and year are useful units of structuring time, because the position of the sun on the sky, which influences our lives, is described by them.
ISO 8601 should however be used to replace notations such as “2/4/95” and “9.30 p.m.”.
Apart from the recommended primary standard notation YYYY-MM-DD, ISO 8601 also specifies a number of alternative formats for use in applications with special requirements.
Especially authors of Web pages and software engineers who design user interfaces, file formats, and communication protocols should be familiar with ISO 8601.
ISO 8601 is only specifying numeric notations and does not cover dates and times where words are used in the representation.
For example, the 53 weeks of the worst case year 1976 started with 1975-12-29 = 1976-W01-1 and ended with 1977-01-02 = 1976-W53-7.
On the other hand, considering the lowest number of the last week of a year, the worst case is a non-leap year like 1999 that starts with a Friday, which ensures that the first three days of the year belong to the last week of the previous year.
The date notation 2/4/5 has at least six reasonable interpretations (assuming that only the twentieth and twenty-first century are reasonable candidates in our life time).
Advantages of the ISO 8601 standard date notation compared to other commonly used variants: As dates will look a little bit strange anyway starting with 2000-01-01 (e.g.
