Last month the French Tennis Federation announced the tournament will begin at Roland Garros on September 20, having originally been scheduled to take place from May 24.
The new date would see the competition start a week after the US Open in New York comes to an end.
It was a move met with widespread criticism and Cuevas, the world number 60, is bemused by the change, considering the impact it will have on players.
"I think the Roland Garros decision was a bit rushed, perhaps without asking the ATP from what I know," the 2008 French Open men's doubles champion told Stats Perform.
"Also, it seems they didn't take into account the rest of the tournaments, the rest of the calendar, it was something weird.
"Even more in this moment of solidarity, where we must have solidarity, it was something pretty selfish to go forward and set the dates without having any concern for the players and the rest of the calendar. All the players were a bit surprised."
While there is still a chance the French Open could be held this year, Wimbledon will not be on the 2020 calendar.
The All England Club this week cancelled the tournament, marking the first time since World War Two that the grass-court grand slam will not take place.
"About the cancellation of Wimbledon, I think it was something pretty obvious," Cuevas added.
"This [coronavirus] is being more serious that what it seemed at the beginning, it's taking a lot to control it, so I think it was a good decision made by the people at Wimbledon."
Cuevas expects it to be a long time before life on the ATP and WTA Tours - which are both suspended - can return to normal.
He said: "We don't know yet when we'll be able to compete again. It's one of the earliest sports to cancel everything and I think it will be one of the latest to get back because of all the nationalities involved.
"Every country must free every airport and flights, so they have to control the pandemic, so that will make us get back after other sports. I don't know when we'll be able to start."
Djere dethroned eighth seed Londero following a 6-7 (5-7) 6-3 7-6 (7-5) victory on the Cordoba clay courts on Friday.
Serbian fourth seed Djere rallied from a set down to earn a semi-final showdown with Schwartzman at the ATP 250 tournament.
World number 14 Schwartzman defeated Spanish fifth seed Albert Ramos-Vinolas 6-0 7-6 (7-0) in one hour, 40 minutes.
Schwartzman, who lost to eventual champion Novak Djokovic in the Australian Open fourth round last month, is eyeing his fourth Tour title and first in his native Argentina.
Cristian Garin – the third seed – and Andrej Martin will meet in the other semi-final.
Garin prevailed 1-6 6-3 6-4 over sixth seed Pablo Cuevas and Martin accounted for Corentin Moutet 6-3 6-2.
The top seed, seeking just a second triumph at Roland Garros, followed up his emphatic win against Tennys Sandgren in round one with a slightly tougher 6-3 6-2 6-4 triumph against Cuevas.
World number one Djokovic had 31 winners to 22 unforced errors and will now face James Duckworth – who beat Ricardas Berankis earlier on Thursday – in the next round.
Djokovic initially took some time to get going and lost his serve in just the third game, before instantly hitting back in the fourth.
The 18-time grand slam winner did not look back from that point, serving up some impressive tennis on the clay and breaking Cuevas again in the eighth game to take a one-set lead.
Cuevas has reached the third round in Paris on four occasions, but hopes of doing so again this year were effectively put to bed in a blistering second set from Djokovic, who was successful with all 11 of his first serves to close in on victory.
Playing on Court Suzanne-Lenglen did not faze Djokovic – with Roger Federer taking prime position on Court Philippe-Chatrier – as he held throughout a gruelling third set and completed the job with a 10th ace of an entertaining contest.
Data Slam: Another milestone reached for Djokovic
Thursday's match was Djokovic's 350th at a grand slam and he looked very impressive pretty much from the moment he recovered from his early wobble. Cuevas also played well, but his opponent saved eight of the nine break points he faced to set up a meeting with Berankis.

Garin, the third seed at the ATP 250 event played on clay, rushed past Hungarian Attila Balazs 6-3 6-0 in just 68 minutes in Argentina.
The Chilean incredibly lost just eight points on serve, while converting five of 16 break points in a dominant performance.
Garin will face Uruguayan sixth seed Pablo Cuevas, who survived a test to get past Italian Gianluca Mager 6-7 (5-7) 7-6 (7-2) 6-1.
Pella, the second seed and last year's runner-up, fell to Frenchman Corentin Moutet after a gruelling contest.
Moutet beat Pella at the French Open last year and he repeated the feat courtesy of a 6-7 (4-7) 7-5 6-3 victory after just over three hours on court.
Slovakian Andrej Martin will face Moutet after overcoming Spanish qualifier Carlos Taberner 6-3 7-6 (9-7).
World number 97 Martinez came through Monday's longest match, which lasted two hours and 43 minutes, as a 6-3 6-7 (4-7) 6-4 winner.
Mikael Ymer, who reached the quarter-finals of last week's Swiss Open Gstaad, is also through to the second round in Austria after battling past Pablo Cuevas 6-3 7-5.
Qualifier Jozef Kovalik will face Jiri Vesely for a place in the quarter-finals, meanwhile, after beating ninth seed Jaume Munar in straight sets.
Also through on Monday was lucky loser Carlos Taberner, who took advantage of his second chance by battling from a set down to overcome Thiago Seyboth Wild 3-6 6-3 6-2.
Eighth seed Opelka took the first set against Pablo Cuevas and passed up three opportunities in a second-set tie-break before succumbing to a 5-7 7-6 (11-9) 7-6 (7-2) defeat.
Fritz, seeded fifth, slipped to a 6-4 7-6 (7-4) loss to Alexander Bublik, who now owns a 2-0 lead in their head-to-head record having also triumphed in Chengdu last year.
In the day's other match, Laslo Djere needed three sets to defeat Alexei Popyrin.
Now unranked, Sock needed a wildcard into the ATP 250 tournament and suffered a 6-3 6-4 loss to fellow American Marcos Giron.
A former world number eight, Sock won just one singles match last year – at the Laver Cup.
Giron created 10 break points and converted four on his way to victory in 76 minutes.
Coming off a run to the Australian Open quarter-finals, Sandgren suffered a 6-7 (5-7) 6-3 7-6 (7-3) loss to Steve Johnson.
Sandgren squandered seven match points in a last-eight loss to Roger Federer in Melbourne and the fifth seed was edged by Johnson.
Sixth seed Miomir Kecmanovic and Italian veteran Andreas Seppi posted wins over Tommy Paul and Damir Dzumhur respectively.
At the Argentina Open, Casper Ruud was the only seed in action and eased past Pablo Andujar 6-2 6-3.
Pablo Cuevas, Federico Delbonis and Thiago Monteiro also moved into the second round.
Verdasco, the seventh seed at the ATP 250 event played on clay, was beaten by qualifier Carlos Taberner 4-6 6-1 6-4 in Argentina.
In a clash between two Spaniards, Taberner – at 198 ranked 149 places below Verdasco – won three of the final four games.
Verdasco had made the quarter-finals in Doha and third round at the Australian Open to begin 2020, but the 36-year-old bowed out in his opener.
Sixth seed Cuevas had no such problems, beating local hope Federico Delbonis 7-5 6-2.
Earlier, Italian Gianluca Mager beat qualifier Juan Pablo Ficovich 6-2 3-6 6-2 and Attila Balazs overcame Lorenzo Sonego 6-2 7-6 (7-3).
