Given a date as input in any convenient format, output a calendar with that date as the exact center of a five-week window. The header of the calendar must include the two-letter abbreviations for the days of the week (i.e., Su Mo Tu We Th Fr Sa
).
For example, given April 2 2019
as input, the output should be
Sa Su Mo Tu We Th Fr
16 17 18 19 20 21 22
23 24 25 26 27 28 29
30 31 1 2 3 4 5
6 7 8 9 10 11 12
13 14 15 16 17 18 19
so that the given date is the exact middle of the calendar.
Given February 19 2020
, output
Su Mo Tu We Th Fr Sa
2 3 4 5 6 7 8
9 10 11 12 13 14 15
16 17 18 19 20 21 22
23 24 25 26 27 28 29
1 2 3 4 5 6 7
For September 14 1752
, show the following:
Mo Tu We Th Fr Sa Su
28 29 30 31 1 2 3
4 5 6 7 8 9 10
11 12 13 14 15 16 17
18 19 20 21 22 23 24
25 26 27 28 29 30 1
- Input and output can be given by any convenient method.
- The input is guaranteed non-empty and valid (i.e., you'll never receive
""
orFeb 31
etc.). - Assume Gregorian calendar for all dates.
- Leap years must be accounted for.
- Input dates will range from
Jan 1 1600
toDec 31 2500
. - You can print it to STDOUT or return it as a function result.
- Either a full program or a function are acceptable.
- Any amount of extraneous whitespace is acceptable, so long as the characters line up appropriately.
Standard loopholes are forbidden.- This is code-golf so all usual golfing rules apply, and the shortest code (in bytes) wins.

If this is an answer to a challenge…
…Be sure to follow the challenge specification. However, please refrain from exploiting obvious loopholes. Answers abusing any of the standard loopholes are considered invalid. If you think a specification is unclear or underspecified, comment on the question instead.
…Try to optimize your score. For instance, answers to code-golf challenges should attempt to be as short as possible. You can always include a readable version of the code in addition to the competitive one.
Explanations of your answer make it more interesting to read and are very much encouraged.…Include a short header which indicates the language(s) of your code and its score, as defined by the challenge.
More generally…
…Please make sure to answer the question and provide sufficient detail.
…Avoid asking for help, clarification or responding to other answers (use comments instead).
