Here is a collection of possible typos I find when translating to finnish.
This bugs are not critical but may be give more accurate impression if they are corrected.

If needed I can make separate postings for each case.

1) 
# Lähde: 1-Jan-1900 po. 1-Jan-1970?
#: ../plugins/fn-date/functions.c:139
msgid "The UNIT2DATE function translates Unix timestamps into date serial values.  Unix timestamps are number of seconds since Midnight 1-Jan-1900."

2)
# Lähde: Sunday po. Tuesday?
#: ../plugins/fn-date/functions.c:615
msgid "If @{method} is 2, then Monday is 1, Sunday is 2, etc."
msgstr "Jos @{method} on 2, niin maanantai on 1, tiistai on 2 jne."

3)
# Lähde: ISO turha?
#: ../plugins/fn-date/functions.c:1075
msgid "WEEKNUM:ISO week number"

(Explanation: Weeknum function can handle other than ISO weeknumbers too?)

4)
# Lähde: _DELTA po. _GAMMA?
#: ../plugins/fn-derivatives/options.c:351
msgid "OPT_BS_DELTA uses the Black-Scholes model to calculate the 'gamma' of a European option struck at @{strike} on an asset with spot price @{spot}. The gamma of an option is the second derivative of its price with respect to the price of the underlying asset."

5)
# Lähde: _DELTA po. _VEGA?
#: ../plugins/fn-derivatives/options.c:452
msgid "OPT_BS_DELTA uses the Black-Scholes model to calculate the 'vega' of a European option struck at @{strike} on an asset with spot price @{spot}. The vega of an option is the rate of change of its price with respect to volatility."

6)
# Lähde: _DELTA po. _RHO?
#: ../plugins/fn-derivatives/options.c:518
msgid "OPT_BS_DELTA uses the Black-Scholes model to calculate the 'rho' of a European option struck at @{strike} on an asset with spot price @{spot}. The rho of an option is the rate of change of its price with respect to the risk free interest rate."

(Expl. 4...6: Maybe it is just copied text of function OPT_BS_DELTA for other similar functions but names are not changed?)

7)
# Lähde: double-declining po. variable declining?
#: ../plugins/fn-financial/functions.c:3247
msgid "VDB calculates the depreciation of an asset for a given period range using the double-declining balance method."

(Expl. there is DDB function for double declining, so here variable?)

8)
# lähde: puuttuuko kaarisulut?
#: ../plugins/fn-info/functions.c:1497
msgid "ERROR.TYPE:the type of @error"
msgstr "ERROR.TYPE: @{error}-tyyppi"

9)
# lähde: text po. name?
#: ../plugins/fn-info/functions.c:1551
msgid "ERROR:the error with name @{text}"
msgstr "ERROR:virhe nimeltään @{name}"

10)
# Lähdevirhe SHEETS po. SHEET?
#: ../plugins/fn-lookup/functions.c:1594
msgid "If @{reference} is neither a reference nor a literal sheet name, SHEETS returns #VALUE!"
msgstr "Jos @{reference} ei ole viite eikä taulukon nimi, SHEET palauttaa #ARVO!-virheen."

11)
# lähde: th po. the?
#: ../plugins/fn-math/functions.c:1494
msgid "SUMSQ:sum of th squares of all values and cells referenced"

12)
# lähde: x po. d?
#: ../plugins/fn-math/functions.c:1617
msgid "x:non-negative integer, defaults to 0"
msgstr "d:ei-negatiivinen kokonaisluku, oletuksena on 0"

13)
# Lähde: SEARCH po. SEARCHB?
#: ../plugins/fn-string/functions.c:1333
msgid "If @{start} is less than one or it is greater than the byte length of @{text}, SEARCH returns #VALUE!"
msgstr "Jos @{start} on vähemmän kuin yksi tai suurempi kuin @{text}-merkkijonon pituus tavuina, SEARCHB palauttaa #ARVO!-virheen."

14)
# lähde: vaikuttaa epäloogiselta, mutta ...
#: ../plugins/fn-tsa/functions.c:914
msgid "Inverse:if false, the inverse Fourier transform is calculated. Defaults to false"

(Expl. It just seems non-logical to use false for YES? but ...)
