\begintext


In this paper we report O$-$C diagrams for 33 RR Lyr type variables. The diagrams 
are based on (1) our observations (light curve data and plots are available in the online version), 
obtained in 2012 to 2016 with the 0.76-m and 1.0-m telescopes of the South African Astronomical Observatory (SAAO) equipped 
with CCDs with $B$, $V$, and $I_{C}$ filters of the Kron-Cousins photometric system (Cousins 1976), (2) the data published by Berdnikov et al.\ (2012) and Le Borgne et al.\ (2007ab, 2008ab, 2009, 2012, 2013), and (3)
the data from NSVS (Wils et al.\ 2006), ASAS-3 (Pojmanski 2002), Catalina (Drake et al.\ 2013) , HIPPARCOS (1997), 
and AAVSO databases. To calculate the O$-$C residuals we used the Hertzsprung (1919) method  as it was computerized 
by Berdnikov (1992). 

Table~2 lists the O$-$C values computed with the  the mean light elements from Table~1. Figs.~1$-$5
show the corresponding O$-$C diagrams, where we use different symbols and colors 
with vertical error bars (which are usually smaller than symbols) for different data: green filled circles and black open circles
for NSVS and HIPPARCOS, respectively; blue and red open squares for Catalina
and ASAS-3, respectively; pluses for Le Borgne and AAVSO, and red filled squares for Berdnikov et al.\ (2012) and our 
observations.

From these O$-$C diagrams one can infer the following. The time interval covered by our study is too 
short for investigating any evolutionary period changes. 
The O$-$C diagrams of AP~Cnc, TV~Lib, PS~Lup, and BT~Sco indicate abrupt period change before the last data 
point. 
Some waves are visible in the O$-$C diagrams for V1184~Cen, V1354~Cen, V559~Hya, QR~Lib, V354~Vir 
and V348~Vir,  but we cannot identify them as periodic variations, because this would require observing
several waves at least. 
The lack of data in some time intervals may lead to a miscalculation of the epoch. 
Examples are the O$-$C diagrams of RT~Equ, IK~Hya, V558~Oph, V1041~Oph, and AF~Sex. 
 The O$-$C diagram of V1017~Oph shows a systematic shift between the ASAS and Catalina data, which
can be explained by the fact that 
 the brightness of this star is close to the limiting magnitude of ASAS.
