v2.24.0
The date and time functions a spreadsheet of schedules needs.
New
WORKDAY,WORKDAY.INTL,NETWORKDAYS,NETWORKDAYS.INTL: step over
weekends and holidays, or count the working days between two dates. The
.INTLpair takes a weekend code or a seven-character pattern such as
"0000011", so a working week that is not Monday to Friday is expressible.WEEKNUMandISOWEEKNUM, includingWEEKNUM's type 21, which is the
ISO system.YEARFRACon all five day-count bases, which is what a term or an
interest calculation divides by.DATEVALUEandTIMEVALUE, which read a date or a time out of text.
Together they rebuild a full timestamp.
Notes
Reversing the two dates given to NETWORKDAYS returns the same count negated,
and YEARFRAC is unaffected by their order, both matching Excel. A weekend
pattern of every day off is #NUM! rather than a count that never finishes.
That takes the engine to 331 function names.
