Hello

There is no automatic way ... you must interpolate.

```---
from a 365 day calendar. I just noted that me previous
--- I changed ispan to fspan for cal360
If you have an array (say) x(time,lat,lon) and time is daily data
(say) 365 days, then, conceptually, each 360-day  calendar
corresponds to 1.01389 (365/360) days of the 365-day calendar
cal365 = fspan(1,365,365)
cal360 = fspan(1,365,360)
xNew  = linint1_Wrap (cal365, x(lat|:,lon|:,time|:),False, cal360,0)

----- current question
If you have an array (say) x(time,lat,lon) and time is unequally
temporally spaced, then, if 'usp365' represent the unequally
spaced time values
esp365 = fspan(1,365,365)   ; euqally spaced time
xNew  = linint1_Wrap(usp365, x(lat|:,lon|:,time|:), False, esp365,0)
