Hello, Today, 10th of July according to my Outlook calendar seems to be week 28 but the "%W" format in Weewx shows week 27. In general this year this format shows one more week than Excel/Outlook/etc.
Somebody knows why? Shouldn't follow ISO8610? https://en.wikipedia.org/wiki/ISO_8601 In this thread ( https://groups.google.com/forum/#!msg/weewx-user/funRVI-T_p0/e58oZtK6AwAJ) says that week number follow the following rule: %W Week number of the year (Monday as the first day of the week) as a decimal number [00,53]. All days in a new year preceding the first Monday are considered to be in week 0. and this is not the same as ISO8610. Why? How can I get the same week number as ISO8610? The rule that ISO follows is: There are several mutually equivalent and compatible descriptions of week 01: - the week with the year's first Thursday in it (the formal ISO definition), - the week with 4 January in it, - the first week with the majority (four or more) of its days in the starting year, and - the week starting with the Monday in the period 29 December – 4 January. Acording to this today, 10th of July of 2019 is W28. Thanks, Ferran -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
