Dear Mr.Crynkar,
Your message is not clear. If you are seeking the advice for one leave with pay or without pay. Computation method of calculation of salary per day depend upon the company. Normally the salary will be divided by calendar month ie 30/31 in case of weekly day of rest is paid with wages. If not paid paid the same shall be divided by 26 days irrespective any month.
