Daily Data || Need Days instead of Year/Months

[mishra-atul5001]

Hi, i have daily data in hand and need to figure out the WEEKS and DAYS instead of YEARS and MONTHS from the FFT conversion.
Tried something like this below:
tmp = pd.DataFrame({'freq':_val_freqs[2: ], 'y':_val_widw_psd[2: ]})
tmp['Weeks'] = 7/tmp['freq']
tmp['Days'] = tmp['Weeks'] * 7
tmp.head()

Can you please confirm the same.!
Help needed ASAP!
