MARKETCAL2

MARKETCAL2( [Yr], [Nms] )
Yr
Optional. Year to generate the calendar for. If omitted, current year is used.
Nms
Optional. Any value will prevent the Holiday Names column from being displayed.

Generate a list of (currently) the ten Holidays the US Stock Market is closed. Can be used to provide the Holiday array for the NETWORKDAYS.INTL and WORKDAY.INTL functions.

MARKETCAL2 will generate the days the market is closed for the year requested or the current year if that option is omitted, and is designed to work in conjunction with the MKTDAYS Lambda function to build an array of dates the market is open. It will generate a two column array with the name of the holiday in the first column, and the date in the second column. The optional second parameter can be any value and will omit the holiday name column.

This is the long overdue replacement for the MARKETCAL function mentioned in my MKTDAYS Lambda post and then had to have removed because it was very wrong!

Multiple years can be strung together using VSTACK. Here's the code:

Excel Formula:
LAMBDA([Yr],[Nms], 
LET( y, IF(ISOMITTED(Yr), YEAR(TODAY()), Yr), f, EDATE("1-1-" & y, 0),
    fs, f - WEEKDAY(f, 3), s, SEQUENCE(54, 7, fs), m, INDEX(s, , 1), 
    mm, MONTH(m), mlk, XLOOKUP(1, mm, m) + 14, wb, XLOOKUP(2, mm, m) + 14,
    gf, FLOOR("5/" & DAY(MINUTE(y / 38) / 2 + 56) & "/" & y, 7) - 36,
    md, XLOOKUP(5, mm, m, , , -1), jt, XLOOKUP(6, mm, m) + 14,
    ld, XLOOKUP(9, mm, m), th, INDEX(s, , 4),
    mth, MONTH(th), tgd, XLOOKUP(11, mth, th) + 21,
    xd, DATE(YEAR(f), {1; 7; 11; 12}, {1; 4; 11; 25}),
    wd, WEEKDAY(xd, 3), yd, IF(wd = 6, xd + 1, IF(wd = 5, xd - 1, xd)),
    sw, IFS( y<1998,
        SWITCH( SEQUENCE(8), 1, INDEX(yd, 1), 2, wb, 3, gf,
            4, md, 5, INDEX(yd, 2), 6, ld, 7, tgd, 8, INDEX(yd, 4)),
        y < 2022,
        SWITCH( 
            SEQUENCE(9), 1, INDEX(yd, 1), 2, mlk, 3, wb, 4, gf,
            5, md, 6, INDEX(yd, 2), 7, ld, 8, tgd, 9, INDEX(yd, 4)),
        TRUE,
        SWITCH(
            SEQUENCE(10), 1, INDEX(yd, 1), 2, mlk, 3, wb, 4, gf,
            5, md, 6, jt, 7, INDEX(yd, 2), 8, ld, 9, tgd, 10, INDEX(yd, 4))),
    hd, IFS( y < 1998,
        { "NewYear's Day"; "President's Day"; "Good Friday"; "Memorial Day";
            "Fourth of July"; "Labor Day"; "Thanksgiving Day"; "Christmas Day"},
        y < 2022,
        { "NewYear's Day"; "Martin Luther King Day"; "President's Day"; 
            "Good Friday"; "Memorial Day"; "Fourth of July"; "Labor Day";
            "Thanksgiving Day"; "Christmas Day" },
        TRUE,
        { "NewYear's Day"; "Martin Luther King Day"; "President's Day";
            "Good Friday"; "Memorial Day"; "Juneteenth"; "Fourth of July";
            "Labor Day"; "Thanksgiving Day";  "Christmas Day"}),
    IF(ISOMITTED(Nms), CHOOSE({1, 2}, hd, sw), sw)
)
Aside from its use with MKTDAYS, it can also be used for the Holidays options in the NETWORKDAYS.INTL and WORKDAY.INTL functions.

This was inspired and used a lot of the work of @Xlambda on his Lambda Post .
Also, I've been trying a way to stack a number of calendars more gracefully than just VSTACK(MARKETCAL2(2021),MARKETCAL2(2022),MARKETCAL2(2023)). Seems like there should be a shorter way to do it using SEQUENCE or something! Please post if you have a better solution!

I have done the same with my function BACKTOTABLE(VSTACK(TOFILE(Table1),TOFILE(Table2))), but the only way I see of appending new tables with with an OfficeScript, which I have implemented using slice and concat.
 
Thank you for mentioning me @jdellasala✌️😉🙏
2 tiny obs. - formula missing leading "=" and trailing ")"
- returns some errors
Anyhow, after you fix the errors, here is a function for stacking, hope is what you wanted.

I know exactly what happened. I used the Advanced Formula Editor to format the code, but it doesn't include the =LAMBDA( or the closing ) for LAMBDA. I managed to remember adding LAMBDA( but as you pointed out forgot the leading = and trailing ). Thanks for the heads up as well as the exact problem. Here's the corrected M Code:

I copied that from an active cell that was working!
AMARKETCAL is nice! That new holiday screws everything up though! Still a lot easier to make a nice, neat list of Market Closed dates for multiple years than just doing a VSTACK! Thanks.
 
A small point. Your function may be using date shortcut(s) that require USA Regional Settings.
see "gf, FLOOR("5/" & DAY(MINUTE(y / 38) / 2 + 56) & "/" & y, 7) - 36,"
I appreciate that your post is primarily for a USA based audience but there is a comment about International users.

Appreciate the feedback! That line determines the date for Good Friday. I see you're from Canada. Did the function give you yesterday as it should have?
If it didn't, I hope I can fix it!
Called without a parameter, it should return this (in US Date Format):

That syntax would yield an error for systems that have the date format dd-mmm-yy.

More conventional code may be
gf, FLOOR(DATE(y, 5, DAY(MINUTE(y / 38) / 2 + 56)), 7) - 36,

I tried Advanced Formula Editor. It does not seem to install as an Add-in; I have to install it each time I want to use the feature.
Is this normal?

I saw it a long time ago and don't think I ever got it fixed!
