About ISO week 16 of 2027
ISO 8601 weeks start on Monday and end on Sunday. Week 16 of 2027 begins on Monday, April 19, 2027 and ends on Sunday, April 25, 2027. Week numbering follows the international standard: week 1 of a year is the week containing the first Thursday of January, which is why some calendar dates near January 1st belong to the previous or next ISO year.
The ISO week system is the standard for business reporting across Europe and much of the world. The US convention differs: weeks start on Sunday and week 1 contains January 1st, so US week numbers can be one ahead of or behind ISO numbers near year boundaries.
