Unless you're using a version prior to R2014b, use datetimes:
>> dn = 736696 + 90*rand(10,1)
dn =
736755.016662924
736699.214051072
736772.421637528
736780.059392298
736757.086163937
736764.196611752
736762.881922131
736731.300431758
736754.993010116
736711.406801903
>> d = datetime(dn,'ConvertFrom','datenum')
d =
10×1 datetime array

04-Jan-2017 05:08:14
18-Mar-2017 10:07:09
26-Mar-2017 01:25:31
03-Mar-2017 02:04:04
10-Mar-2017 04:43:07
08-Mar-2017 21:09:58
05-Feb-2017 07:12:37
28-Feb-2017 23:49:56
16-Jan-2017 09:45:47
>> (d.Month == 3)
ans =
10×1 logical array

Prior to 14b, use datevec.
